Electrophilic Substitution Reactions of Haloarenes

Q.

How do you convert benzene to diphenyl?

Q.

An alkyl halide with molecular formula C₆H₁₃Br on dehydro halogenation gave two isomeric alkenes X and Y with molecular formula C₆H₁₂. On reductive Ozonolysis, X and Y gave four compounds CH₃COCH₃, CH₃CHO, CH₃CH₂CHO and (CH₃)₂ CHCHO. The alkyl halide is

1. 2 - Bromo hexane

2. 2, 2 - Dimethyl - 1 - bromobutane

3. 2 - Bromo - 2, 3 - dimethyl butane

4. 3 - Bromo - 2 - methyl pentane
