Options
- AA B C IV I III
- BA B C II III V
- CA B C IV III I .
- DA .B C II I III
Correct answer
D. A .B C II I III
Step-by-step solution
Boron hydride is an electron deficient species so, it act like and Lewis acid and carbon monoxide act as a Lewis base and form a co-ordinate bond. B 2 H 6 + CO   ⟶   2 BH 3 · CO It is oxidised with air. B 2 H 6 + 3 O 2 ⟶   B 2 O 3   +   3   H 2 O It is hydrolysed with water to give B 2 H 6 + 6 H 2 O ⟶   2 H 3 BO 3   +   6   H 2
