Which of the following compound gives only one monochloro product on its chlorination in presence of sunlight?
1 $\mathrm{n}$ - butane
2 Iso pentane
3 Neo pentane
4 $\mathrm{n}$ - pentane
Explanation:
: The chlorination of neo pentane with $\mathrm{Cl}_2$ in the presence of diffused sunlight gives only one monochloro compound, Neo pentane or 2, 2-dinethyl propane has only primary hydrogen hence it can give only monochloro derivative.

Alkyl halides reacts with dialkyl copper reagents to give :
1 Alkenyl halides
2 Alkanes
3 Alkyl copper halides
4 Alkenes
Explanation:
: Alkyl halides react with dialkyl copper reagents to form a alkane, this reaction is known as Corey House synthesis. $\mathrm{R}^{\prime}-\mathrm{X}+\mathrm{R}_2 \mathrm{CuLi} \rightarrow \mathrm{RR}^{\prime}+\mathrm{RCu}+\mathrm{LiX}$

The nitration (using nitration mixture) of aniline gives
1 p-nitroaniline
2 o-nitroaniline
3 m-nitroaniline
4 all the above
Explanation:
: Nitration of aniline yields tarry oxidation products in addition to the nitro derivatives. In strongly acidic medium aniline is protonated to form a aniline union and mixture of ortho, Para and meta nitro-aniline is formed.
