Question

In the given image, X will be:

• A. $\mathrm{R}-\mathrm{HC}=\mathrm{O}.$
• B. $\mathrm{R}-{\mathrm{CH}}_2{\mathrm{NH}}_2$
• C. $\mathrm{R}-\mathrm{COOH}$
• D. $\mathrm{R}-{\mathrm{NH}}_2$

Answer 1

The correct option is A

$\mathrm{R}-\mathrm{HC}=\mathrm{O}.$

The correct option is A.

1. $\mathrm{DiBAl}-\mathrm{H}$ is basically acts as a reducing agent.
2. reduction of cyanide group can be led to the formation of$\mathrm{R}-{\mathrm{CH}}_2{\mathrm{NH}}_2$or $\mathrm{R}-\mathrm{HC}=\mathrm{O}.$
3. due to $\mathrm{DiBAl}-\mathrm{H}$ classical reduction will takes place which leads to the formation of aldehydic compound.
