Question

Condiser the following reaction:
$C_2{H}_{5}Cl+AgCN\stackrel{EtOH/H_{2}O}{\to }X\left(major\right)$
which one of the following statements is true for X?

• A. It gives propionic acid on hydrolysis
• B. It has an ester function
• C. It has a nitrogen linked to ethyl carbon
• D. It has a cyanide group

Answer 1

Answer: (C)

It has a nitrogen linked to ethyl carbon

The bond between AgCN is not just same, it will not easily broke as the bond between C and N in AgCN is triple bond . AgCN is mainly covalent in nature and nitrogen is free to donate electron pair forming isocyanide as the main product.

In the presence of $EtOH/H_{2}O$

$C_2{H}_5-Cl$ + $AgCN$ $\to$ $C_2{H}_5-NC$ + $AgCl$

X = $C_2{H}_5-NC$

Since, It has a nitrogen linked to ethyl carbon.

Since , Option C is correct.
