Match List-I with List-II:

1. ${\text{PCl}}_5$: $s{p}^{3}d$ hybridization $\to$ Trigonal bipyramidal (iv).2. ${\text{SF}}_6$: $s{p}^3{d}^2$ hybridization $\to$ Octahedral (iii).3. ${\text{BrF}}_5$: $s{p}^3{d}^2$ with 1 lone pair $\to$ Square pyramidal (i).4. ${\text{BF}}_3$: $s{p}^2$ hybridization $\to$ Trigonal planar (ii).Correct sequence: (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii).
