Answer: The bond angle in methane compound is 109.5°
Explanation:
The chemical formula of methane molecule is \(CH_4\)
The equation used to calculate hybridization follows:
\(\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]\)
where,
V = number of valence electrons present in central atom
, carbon = 4
N = number of monovalent atoms bonded to central atom = 4
C = charge of cation
A = charge of anion
Putting values in above equation, we get:
\(\text{Number of electron pair}=\frac{[4+4]}{2}=4\)
The number of electron pair are coming out to be 4. This means that the hybridization will be \(sp^3\) and the electronic geometry of the molecule will be tetrahederal.
The bond angle between the atoms when the electronic geometry is tetrahederal is 109.5°
The image of the methane molecule is attached below.
Hence, the bond angle in methane compound is 109.5°
