Question: In the following reaction ‘A’ is $ \begin{align} & C_2H_5MgBr+H_2C-CH_2\xrightarrow{H_2O}A \\ & \overset{\backslash /}{\mathop{O}} \\ \end{align} $

[MP PET 1994; CBSE PMT 1998]

Options:

A) $ C_2H_5CH_2CHO $

B) $ C_2H_5CH_2CH_2OH $

C) $ C_2H_5CH_2OH $

D) $ C_2H_5CHO $

Show Answer

Answer:

Correct Answer: B

Solution:

$ C_2H_5MgBr+\underset{\overset{}{\mathop{\overset{\backslash /}{\mathop{O}}}}}{\mathop{H_2C-CH_2}}\xrightarrow{H_2O} $

$ \underset{n\text{-butyl}alcohol}{\mathop{\underset{(A)}{\mathop{C_2H_5CH_2CH_2OH}}}}+MgBr(OH) $
