Question

according to the vsepr theory, the shape of a covalent molecule depends upon the
a number of electron pairs in the valence shell of the central atom
b bond pair electron
c lone pair electron
d all of the above
check it

Explanation:

The VSEPR (Valence - Shell Electron - Pair Repulsion) theory states that the shape of a covalent molecule depends on the number of electron pairs (bond - pair and lone - pair) in the valence shell of the central atom. The electron pairs (both bonding and non - bonding) around the central atom repel each other and try to stay as far apart as possible to minimize the repulsion. So, all the factors (number of electron pairs in the valence shell of the central atom, bond - pair electrons, and lone - pair electrons) contribute to determining the shape of the molecule.

Answer:

D. All of the above
