Identify a pair of molecules having similar shapes of both members.

Options

  1. ANH ₃,~~ SO ₂
  2. BXeF ₄,~~ SF ₄
  3. CH ₂ O ,~~ SCl ₂
  4. DPCl ₅,~~ BrF ₅

Correct answer

C. H ₂ O ,~~ SCl ₂

Step-by-step solution

Molecular shapes are determined using Valence Shell Electron Pair Repulsion theory, analyzing bonding pairs and lone pairs around the central atom. NH ₃ has trigonal pyramidal geometry (steric number 4, 1 lone pair), while SO ₂ is bent (steric number 3, 1 lone pair)—different shapes. XeF ₄ is square planar (steric number 6, 2 lone pairs), while SF ₄ is see-saw (steric number 5, 1 lone pair)—different shapes. PCl ₅ is trigonal bipyramidal (steric number 5, 0 lone pairs), while BrF ₅ is square pyramidal (steric numbe
