According to VSEPR theory, the electrons create a negatively charged atmosphere around the atomic nuclei and this creates a repulsive force among the like charges. Unsymmetrical geometry, the nature of the bonds, and the presence of a dipole moment are some of the factors that make a molecule polar. The molecular formula of structure (A) is C6H10O and it is not an isomer. C- 4 valence electron. Required fields are marked *. Carbon has a steric number of 4 as it has four valence electrons in its outer shell. This is represented in the figure below.
