Question

Match the column I with column II and mark the appropriate choice.

	Column I		Column II
(A)	$C_2{H}_2$	(i)	${\text{sp}}^3{d}^2$ hybridisation
(B)	$S{F}_6$	(ii)	${\text{sp}}^3{d}^3$ hybridisation
(C)	$S{O}_2$	(iii)	$\text{sp}$ hybridisation
(D)	$I{F}_7$	(iv)	${\text{sp}}^2$ hybridisation

• A. (A) $\to$ (i), (B) $\to$ (iii), (C) $\to$ (ii), (D) $\to$ (iv)
• B. (A) $\to$ (iii), (B) $\to$ (i), (C) $\to$ (iv), (D) $\to$ (i)
• C. (A) $\to$ (ii), (B) $\to$ (iii), (C) $\to$ (i), (D) $\to$ (iv)
• D. (A) $\to$ (iv), (B) $\to$ (i), (C) $\to$ (iii), (D) $\to$ (ii)

Answer 1

Answer: (B)

(A) $\to$ (iii), (B) $\to$ (i), (C) $\to$ (iv), (D) $\to$ (i)

$C_2{H}_2$	$sigmabonds$ = $2$ , lone pair $0$	$SP$
$S{F}_6$	$6$ bond pairs, $0$ lone pair	$S{P}^3{d}^2$
$S{O}_2$	$2$ bond pairs, $1$ lone pair	$S{P}^2$
$I{F}_7$	$7$ bond pairs,$0$ lone pair	$S{P}^3{d}^3$

So the correct option is [B].
