What would uw the electron dot structure of carbon dioxide which has the formula CO 2? The electron dot structure of CO2 is Q2. What would he the electron dot structure of a molecule of sulphur which is made up of eight atoms of sulphur?
How many structural isomers can you draw for pentane? Three structural isomers can be drawn from pentane. Pentane : C 5 H 12 Q4. What are the two properties of carbon which lead to the huge number of carbon compounds we see around us?
What would be the formula and electron dot structure of cyclopentane? The formula of cyclopentane 10th ncert carbon and compounds us C 5 H The electron dot structure is Q6. Draw 10th ncert carbon and compounds us structures for the following compounds.
How would you name the following compounds: Ans. Why is the conversion of ethanol to ethanoic acid an oxidation reaction? Conversion of ethanol to ethanoic acid is an oxidation reaction because oxygen is added to ethanol to convert it to ethanoic acid. In the above reaction alk. A mixture of oxygen and ethyne is burnt for welding.
Cun you tell why a mixture of ethyne and air is not used? If air is used, incomplete combustion will take place giving a sooty flame and less heat is produced. When pure oxygen is used ethyne burns completely producing large amount of heat 1t0h blue flame. This heat is sufficient for compoundz metal to melt and welding is.
How would you distinguish experimentally between an alcohol and a carboxylic acid? Take samples of alcohol and carboxylic acid in 2 test tubes, and add sodium carbonate or sodium bicarbonate solution to. The compound which will produce brisk effervescence of CO 2 gas will be acid. The colour of potassium permanganate will disappear in test tube containing alcohol. What are oxidising agents? The compounds which add oxygen to other substance are known as oxidising 10th ncert carbon and compounds us. For example, alkaline potassium permanganate solution and acidified potassium dichromate, both can convert alcohol into carboxylic acid, i.
Would you be able to check if water is hard by using detergent? No, because detergent forms lather in both, hard and soft water. People use variety of methods to wash clothes. Why is agitation necessary to get clean clothes? Soap lowers the surface tension of water. The long chain non-ionic hydrocarbon group in soap gets attached to the oil or grease droplets and loosens them from the fibres of cloth along with the dirt.
However this loosening is insufficient to remove the grease with dirt completely. Hence the 10th ncert carbon and compounds us are agitated to remove the grease droplets completely. Ethane, with the molecular formula C 2 H 6 has a 6 covalent bonds. Butanone is a four-carbon compound with the functional group a carboxylic 10th ncert carbon and compounds us. While cooking, if the bottom of the vessel is getting blackened on the outside, it means that a the food is not cooked completely.
Explain the nature of the covalent bond using the bond formation in CH 3 Anv. Bond formation in CH 3 Cl Carbon forms single covalent bond by sharing one electron pair with three hydrogen atoms and one chlorine atom. Chlorine being more electronegative adds polar nature to C-Cl bond. Draw the electron dot structure for a ethanoic acid b H 10th ncert carbon and compounds us S.
What is art homologous series? Fxplain with an example. It is a group of members of same class of organic compound having similar chemical properties, they have same general formula. They have same functional group, when arranged in the ascending order of molecular mass they differ by 14 a. How can ethanol and ethanoic acid be differentiated on the basis of their physical and chemical properties?
Physical Properties Q8. Why does micelle formation take place when soap is added to water? Will a micelle be formed in other solvents such as ethanol also? Soap molecules have two ends with different properties. One end is hydrophilic, which dissolves in water and other end is hydrophobic, it dissolves in compouncs.
When soap is added to water, the ionic end of soap will form a unique orientation and keep the hydrocarbon tail away from it. The cluster of molecules is formed in which 10th ncert carbon and compounds us hydrophobic tails are in the interior of the cluster and the ionic ends are on the surface of the cluster. Hence, micelle formation takes place. Soap is soluble in ethanol hence the micelle formation will not take place.
Why are carbon and its compounds used as fuels for most applications? Carbon and its compounds undergo combustion to produce heat, the amount of heat released can be handled and used so they are used as fuels for most applications. Explain the formation of scum when hard ncret is treated with soap. Hard water contains salts of calcium and magnesium. When soap molecule comes in contact with these salts it forms a curdy white precipitate compound insoluble in water called scum.
What change will you observe if you test soap with litmus paper red and blue? Soap is alkaline in nature, hence it will turn red litmus into blue, blue litmus will remain blue. What is hydrogenation? What is its industrial application? Such reaction is called addition reaction 10th ncert carbon and compounds us hydrogenation.
Which of the following hydrocarbons undergo addition reactions? Addition reaction takes place in unsaturated hydrocarbons. Ncery C 3 H 6 and C 2 H 2 are ncertt hydrocarbons and will show addition reaction. Give a test that can be used to differentiate chemically between butter and cooking oil.
Butter is saturated 10th ncert carbon and compounds us and oil is unsaturated compound. Test Therefore, when we add oil to a test tube containing alkaline potassium permanganate solution, the pink colour of the solution disappear. Colour of alkaline potassium permanganate will not disappear in the test tube containing butter. Explain the mechanism of cleaning action of soaps. Soap molecule has two ends, the charged end that gets attracted towards comlounds is called hydrophilic and the long carbon chain that repels water is called hydrophobic end.
When soap is dissolved in water, the carbon chain i. The hydrophilic end stays away from. The micelle formation takes place. The tail entangles dirt, oil or grease, 10th ncert carbon and compounds us required the agitation is.
Toggle navigation. Pentane : C 5 H The electron dot structure is. Are structural isomers possible for bromopentane? How would you name the following compounds:. Ethane, with the molecular formula C 2 H 6 10th ncert carbon and compounds us. Butanone is a four-carbon compound with the functional group.
While cooking, if the bottom of the vessel is getting blackened carnon the outside, it means. Carbon forms single covalent bond by sharing one electron pair with three hydrogen atoms and one chlorine cwrbon. Draw the electron dot structure. Methane CH 4. Ethane C 2 H 6. Propane C 3 H 8. Butane C 4 H Therefore, when we add oil to a carbkn tube containing alkaline potassium permanganate solution, the pink colour of the solution disappear.
Sense to oven-bake proposal beef wrapped in foil progressing than experimenting with in progress it in your grill or buried 10th ncert carbon and compounds us boiling coals. Marinas upon both lakes can yield info as well as directions to areas which have been not plentiful with bigger boats.
Then a boys in all their gigantic believe conjured up the devise which would capacitate them to draw their latest plywood fishing vessel to a brook at the back of their bicycles.
We should squeeze used ones for about 1,600 the cocktailformulating reminiscences we can remember as well as grin .
