In diborane, the two $H - B - H$ angles are nearly
$60^°$, $120^°$
$95^°$, $120^°$
$95^°$, $150^°$
$120^°$, $180^°$
Hydrogen gas will not reduce
Give suitable laboratory preparation for diborane.
Group $13$ elements show $+1$ and $+3$ oxidation states. Relative stability of $+3$ oxidation state may be given as
The correct formula of borax is
The formation of molecular complex $BF_3 - NH_3$ results in a change in hybridization of boron
