Q13 / 160 · AP EAMCET 2019 (22 Apr Shift 1) · Chemistry

What is \(X\) in the following reaction? \(\mathrm{NaH}+\mathrm{B}_2 \mathrm{H}_6 \xrightarrow{\text { Diellhyl ether }} X\)

  • Correct answer
    A
    \(\mathrm{Na}\left[\mathrm{BH}_4\right]\)
  • B
    \(\mathrm{NaBO}_2\)
  • C
    \(\mathrm{H}_3 \mathrm{BO}_3\)
  • D
    \(\left(\mathrm{C}_2 \mathrm{H}_5 \mathrm{OC}_2 \mathrm{H}_4\right)^{+}\left(\mathrm{BH}_4\right)^{-}\)

Solution

Sodium hydride react with diborane to produce sodium tetrahydroxoborate III. \(\left.\mathrm{NaH}+\mathrm{B}_2 \mathrm{H}_6 \xrightarrow{\text { Diethyl ether }} 2 \mathrm{Na}{ }^{\prime} \mathrm{BH}^{\prime} \mathrm{B}_4\right]\) Hence, \(X\) is \(\mathrm{Na}\left[\mathrm{BH}_4\right]\).

Hence, the correct answer is option: 'A'.
