Chemistry Question on p -Block Elements

All of the following give orthoboric acid except

A

\ceB2H6+H2O−>\ce{B_2H_6 + H_2O ->}

B

\ceB2H6+HCl−>\ce{B_2H_6 + HCl ->}

C

\ceNa2B4O7+H2SO4(aq)−>\ce{Na_2B_4O_7 + H_2SO_4 (aq) ->}

D

\ceCa2B6O11+SO2(aq)−>\ce{Ca_2 B_6 O_{11} + SO_2 (aq) -> }

Answer

\ceB2H6+HCl−>\ce{B_2H_6 + HCl ->}

Explanation

Solution

B2H6+HCl−>B2H5Cl+H2 {B_2H_6 + HCl -> B_2H_5Cl + H_2} (a) B2H6+6H2O−>2H3BO3+6H2 {B_2H_6 + 6H_2O -> 2H_3BO_3 + 6H_2} (c) Na2B4O7+H2SO4+5H2O−>Na2SO4+4H3BO3 {Na_2B_4O_7 + H_2SO_4 + 5H_2O -> Na_2SO_4 + 4H_3BO_3} (d) Ca2B6O11+4SO2+11H2O−>2Ca(HSO3)2+6H3BO3 { Ca_2B_6O_{11} + 4SO_2 + 11H_2O -> 2Ca (HSO_3)_2 + 6H_3BO_3}
