a ) CH3
a) aroma
b) -OH
a) -COOH
a) CH3-COOH
a) Halo
Q.2) SHORT ANSWER QUESTIONS.
1.) The hydrocarbons contain carbon carbon single bond is known as saturated hydrocarbons.
2.) The hydrocarbons contain carbon carbon double and triple bond is called as unsaturated hydrocarbons.
3.) IUPAC is International Union of Pure and Applied Chemistry. Is an international organisation that carry new trends in the field of chemical science.
4.) a) methane
- molecular formula CH4
- structural formula
Q.3) SHORT ANSWER QUESTIONS.
1.) aromatic compounds are cyclic compounds having their own aroma. Benzene is an aromatic compound.
Structural formula of benzene:- C6H6
2.) compounds having same molecular formula but different chemical and physical properties are called isomers. The phenomenon is called Isomerism.
- Chain Isomers
- Functional Isomers
- Position Isomers
3.) complete the table
4) The presence of certain atoms or groups imparts certain characteristic properties to organic compounds. They are called as functional groups.
Vinegar is a carboxylic acid. Its formula is CH3-COOH.
IUPAC name :- Ethanoic acid.
5) In saturated hydrocarbons, all valencies of hydrocarbons are satisfied by hydrogen. When a hydrogen atom is removed from an alkene , it changes to a reactive group of atom these are radicals. The radical formed by removal of hydrogen atom from methane is called methyl radical.
Example :-
-CH3 , -CH2-CH3 ,
