Hydrocarbons Question 8

Question: If HCl is added over $ CH_2=C<\begin{matrix} CH_3 \\ CH_3 \\ \end{matrix} $ then what is formed [CPMT 1996]

Options:

A) $ \underset{Cl}{\mathop{\underset{|}{\mathop{CH_2}}}}=C<\begin{matrix} CH_3 \\ CH_3 \\ \end{matrix} $

B) $ \underset{}{\mathop{\underset{}{\mathop{CH_2}}}}-CH<-\begin{matrix} Cl \\ CH_3 \\ CH_3 \\ \end{matrix} $

C) $ $ $ \underset{}{\mathop{\underset{}{\mathop{CH_2}}}}=C<\begin{matrix} CH_3 \\ CH_2Cl \\ \end{matrix} $

D) None of these

Show Answer

Answer:

Correct Answer: B

Solution:

$ CH_2=\underset{CH_3}{\mathop{\underset{|}{\mathop{C-}}C}}H_3+\overset{}{\mathop{HCl}}\to \underset{\begin{smallmatrix} \text{2-chloro-2-methyl} \\ propane \end{smallmatrix}}{\mathop{CH_3-\underset{CH_3}{\overset{Cl}{\mathop{\underset{|}{\overset{|}{\mathop{C-}}}}}}CH_3}} $
