Question

Match the correct combination :

Column I	Column II
A) $B_2{H}_6$	P) Lewis acid
B) $B{F}_3$	Q) Tetrahedral
C) $AlC{l}_3$	R) $s{p}^3$ hybridisation
D) $B{H}_4^{-}$	S) Planar molecule

• A. $A\to P,Q,R;B\to P,S;C\to P,S;D\to Q,R$
• B. $A\to P,S;B\to P,S;C\to Q,R;D\to P,S$
• C. $A\to Q,R;B\to P,S;C\to R,S;D\to P,S$
• D. $A\to P,S;B\to P,S;C\to Q,R;D\to R,S$

Answer 1

The correct option is A $A\to P,Q,R;B\to P,S;C\to P,S;D\to Q,R$

$B_2{H}_6:B-s{p}^3\text{Hybridisation}$, Tetrahedral, Lewis acid
$B{F}_3:B-s{p}^2$ Hybridisation, $\text{planar - Lewis acid}$
$AlC{l}_3:Al-s{p}^2$ Hybridisation - Planar and Lewis acid
$BH{{}_4}^{-}:B-s{p}^{{}^3}$ Hybridisation, Tetrahedral
