Question

Which hybird orbital are used by carbon atom in CH3OH

Answer 1

One of the sp3 hybrid orbitals overlap with an sp3 hybridized orbital from carbon to form the C-O sigma bond. Both the sets of lone pair electrons on the oxygen are contained in the remaining sp3 hybridized orbital. Due to the sp3 hybridization  the oxygen has a tetrahedral geometry.

Answer 2

for carbon SP3 and for oxygen SP3
