Question

Explain the addition and substitution reaction with the help of examples.
C2H6 undergoes substitution reaction but not addition reaction. ​

Answer 1

alkanes undergo substitution reaction while alkenes undergo addition reactions so (i), (iv) and (v) will undergo substitution reaction as they are alkanes.

Answer 2

Answer:

Explanation:

Saturated hydrocarbons (alkane general formula CnH2n+2) undergo substitution

reactions.

Being saturated hydrocarbons C2H6, C3H8, and CH4, the molecule already has

maximum number of hydrogen atoms it can accommodate and thus, they do not

undergo addition reactions.

Unsaturated hydrocarbons (alkenes CnH2n and alkynes CnH2n−2) undergo addition

reactions. Being unsaturated hydrocarbons, C3H6 and C2H2, the double and triple

bonds can be converted to single bonds and thus such compounds undergo addition

reactions.
