Alkyl halides react with dialkyl copper reagents (Gilman reagents) to give:

Which of the compounds will react faster in an $S_N1$ reaction?
$CH_3-CH_2-Cl$ and $C_6H_5-CH_2-Cl$

Explain the mechanism of the following reaction: $CH_3Cl + OH^-_{(aq)} \to HO-CH_3 + Cl^-$

Explain why:
$(i)$ the dipole moment of chlorobenzene is lower than that of cyclohexyl chloride?
$(ii)$ alkyl halides,though polar,are immiscible with water?
$(iii)$ Grignard reagents should be prepared under anhydrous conditions?

Assertion : Benzyl bromide when kept in acetone water,it produces benzyl alcohol.
Reason : The reaction follows $S_{N}2$ mechanism.

The major product of the following reaction is:
