Answer: 1. (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

Key idea: use VSEPR to find shapes.

  • \(\mathrm{PCl_5}\): 5 bond pairs, trigonal bipyramidal (iv)
  • \(\mathrm{SF_6}\): 6 bond pairs, octahedral (iii)
  • \(\mathrm{BrF_5}\): 5 bond pairs + 1 lone pair, square pyramidal (i)
  • \(\mathrm{BF_3}\): 3 bond pairs, trigonal planar (ii)

So (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii).
