A compound (A) of boron reacts with $NMe_{ 3}$ to give an adduct (B) which on hydrolysis gives a compound © and hydrogen gas. Compound © is an acid. Identify the compounds A, B and C. Give the reactions involved.


#2

Since, compound ‘A ’ of boron reacts with $NMe_{ 3}$ to form an adduct ‘B’. Thus, compound ‘A’ is a Lewis acid. Since, adduct ‘ B’ on hydrolysis gives an acid ‘C’ and hydrogen gas, therefore, ‘ A’ is $B_{ 2}$$H_{ 6}$ and ‘C is boric acid.
