• Correct answer
  A

  (i) $\left(\mathrm{BH}_3\right)_2$ (ii) $\mathrm{H}_2 \mathrm{O}_2 / \mathrm{OH}^{-} ; \mathrm{HCl}, \mathrm{ZnCl}_2$
• B

  (i) $\left(\mathrm{BH}_3\right)_2$ (ii) $\mathrm{H}_2 \mathrm{O}_2 / \mathrm{OH}^{-} ; \mathrm{NaCl}$
• C

  dil. $\mathrm{H}_2 \mathrm{SO}_4 ; \mathrm{HCl}, \mathrm{ZnCl}_2$
• D

  dil. $\mathrm{H}_2 \mathrm{SO}_4 ;$ Conc. HCI
