Haloalkanes and...

The main difference in C - X bond of a haloalkane and a haloarene is 

An alkyl halide on reaction with sodium in the presence of ether gives 2,2,5,5-tetramethylhexane. The alkyl halide is:

Statement 1: $$S_{N}2$$ reaction is carried out in the presence of polar aprotic solvents. 

One of the iosmers of $$C_{4}H_{9}Cl$$ by Wurtz reaction forms $$2,2,3,3$$- tetramethylbutane. The structure of that isomer of $$C_{4}H_{9}Cl$$:

The compound $$Y$$ is:

Assertion: Aryl halides undergo electrophilic substitution more readily than benzene.
Reason: Aryl halide gives a mixture of $$o -, p -$$ products when they undergo electrophilic substitution.

Which one of the following occurs by an addition elimination mechanism?

The major product of the above shown reaction is :
