If P pure orbitals are used in forming the C-H bonds in CH₄ angle of 90° would be expected The observed angles are 109° each. What concept might be useful in explaining the observed angles? Answer: Hybridization

The tetrahedral bond angles (109.5°) in CH₄ cannot be explained using pure s or p orbitals. The concept of hybridization combines one s and three p orbitals to form four equivalent sp³ hybrid orbitals, explaining the observed bond angles in methane.
