Question
Differentiate between alkanes and alkenes. differentiate alkynes from each of these.
R v supposed 2 differentiate altogether orbetween alkanes and alkenes first then differentiate between alkynes in one column and alkanes and alkenes together in second column.

Solution
Alkanes
Alkenes
Alkynes
Alkanes are hydrocarbons that consists of only single covalent bond . They can be starigh chain or branched chain.
General Formula : CnH2n+2
for eg : CH4 ,C2H6 (CH3-CH3),
CH3-CH2-CH2-CH3
Alkenes are hydrocarbons that contain atleast one double covalent bond that is -C=C-.
General formula:
CnH2n
For eg :
CH3-CH=CH2
CH3-CH2-CH=CH2
Alkynes are hydrocarbon that contain atleast one triple covalent bond that is –C≡C–
General formula :
CnH2n-2
For eg :
HC≡CH
CH3–C≡C–CH3
