Answer:
CH2O
Explanation:
According to the valence shell electron pair repulsion theory, electron pairs tend to position themselves as far apart in space as possible to minimize repulsion.
The shape of a molecule depends on the number of electron pairs present on the valence shell of the central atom in the molecule- both lone pairs and bond pairs.
CH2O has three electron domains. the possession of three electron domains and no lone pairs of electrons on the central atom corresponds to a trigonal planar geometry.
