Answer: If molecular geometry is tetrahedral, there are four bond pairs of electrons and thus hybridization is \(sp_3\)
Explanation: Formula used
\(:{\text{Number of electrons}} =\frac{1}{2}[V+N-C+A]\)
where, V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
The number of electrons is 4 for tetrahedral shape that means the hybridization will be \(sp^3\).
The electron pairs will try to minimize the repulsions and will occupy a position of maximum stability. This molecule is made up of 4 equally spaced \(sp^3\) hybrid orbitals forming bond angles of \(109.5^0\)
