Which of the following is an electron deficient molecule?
$LiH$
$B_2H_6$
$LiBH_4$
$B_3N_3H_6$
Explain the following :
$(1)$ Gallium has higher ionisation enthalpy than aluminum.
$(2)$ Boron does not exist as $B^{3+}$ ion.
The formation of molecular complex $BF_3 - NH_3$ results in a change in hybridization of boron
In the thermite process the reducing agent is
Boron forms $BX_3$ type of halides. The correct increasing order of Lewis-acid strength of these halides is
In the reaction ${B_2}{O_3} + C + C{l_2} \to A + CO.$ The $A$ is
