Expert Answer:

Dear Tanishqa,

Please ask one question at a time by which we can explain the topic or concept properly.

Answer to your first question is given below.

Saturated hydrocarbons: In this type of hydrocarbons, the carbon atoms are connected by a single covalent bond. These are called alkane and general formula CnH2n+2 where n=1,2,3….etc. These are less reactive as they contain strong sigma bond. For example: CH4.

Unsaturated hydrocarbons: In this type of hydrocarbons, the carbon atoms are connected by multiple bonds like double or triple bonds. The double bonded compounds are called alkene and has general formula CnH2n and triple bonded compounds are called alkynes and has general formula CnH2n-2. These are more reactive as they contain one or more pi bonds which can be easily broken. For example: CH2=CH2 is an alkene.

Distinguishing test: Saturated hydrocarbons do not undergo hydrogenation reaction while unsaturated hydrocarbons undergo hydrogenation reaction.
