Identify a pair of molecules having similar shapes of both members.
Options
- ANH ₃,~~ SO ₂
- BXeF ₄,~~ SF ₄
- CH ₂ O ,~~ SCl ₂
- 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
