Answer :
The every atom in H₂CO molecule has bond angle is 120 °. the bond angle HCH is 116 ° and The bond angle of H₂CO is 122°.
The H₂CO has trigonal planar molecular geometry. the H₂CO has the same electron geometry that is trigonal planar. The every atom atom attached to the central atom has bond angle is 120 °. the central atom is surrounded by three regions of the electron density. according to the VSEPR theory the molecular geometry is trigonal planar. The H₂CO is the polar molecular. the hybridization is sp².
Thus, the bond angle in H₂CO is 120 ° and the molecular geometry is trigonal planar.
