Question

Compare properties of alkenes and alkynes.

Answer 1

Alkenes-
1. they are unsaturated hydrocarbons with double covalent bonds.
2. common formula:$C_n{H}_{2n}$
3. They have high reactivity.
4. they undergo addition reaction and polymerization.
5. they decolourise bromine solution.
6. they don't undergo substitution reaction.

Alkynes-
1. they are highly unsaturated hydrocarbons with triple bonds.
2. common formula: $Cn{H}_{2n-2}$
3. they have very high reactivity.
4. they undergo addition reaction and polymerization.
5. they decolourise bromine solution.
6. they don't undergo substitution reaction.
