Solution

The correct option is D hydrogen
Since compound $^{'} A^{'}$ of Boron reacts with ${N M e}_{3}$ to form an adduct $^{'} B^{'}$ . Thus compound $^{'} A^{'}$ is lewis acid. Hydrolysis of $^{'} B^{'}$ gives an acid $^{'} C^{'}$ and hydrogen gas.

Diborane $(A)$ $B_{2} H_{6} + {2 N M e}_{3} ⟶ {2 B H}_{3} \cdot {N M e}_{3}$ Adduct $(B)$

${B H}_{3} \cdot {N M e}_{3} + 3 H_{2} O ⟶ H_{3} {B O}_{3} + {N M e}_{3} + 6 H_{2}$ Boric Acid $(C)$
