Q. Benzene is obtained by

1. Substitution of three acetylene molecules
2. Addition of three $C_2{H}_2$ molecules
3. Polymerisation of three $C_2{H}_2$ molecules
4. Condensation of three $C_2{H}_2$ molecules

Q. Benzene easily shows

1. Ring fission reactions since it is unstable.
2. Addition reactions since it is unsaturated.
3. Electrophilic substitution reactions due to stable ring and high electron density.
4. Nucleophilic substitution reactions due to stable ring and minimum electron density.
