Question

According the VSEPR theory the geometry of a covalent molecules depends upon
(A) The number of bond pairs of electrons
(B) The number of lone pairs of electrons
(C) The number of electron pairs present in the outer shell of the central atom
(D) All of the above

Answer 1

Answer is option (C) ,The number of electron pairs present in the outer shell of the central atom.

Explanation : VSEPR theory is abbreviated name of Valence shell electron pairs repulsion theory.

According to this theory, the shape of any covalent molecule is predicted from the electron pairs that surround the central atom of molecules.

If the central atom has only bond pairs its geometry will be symmetrical but if the central atom has both bond pairs and lone pairs, its shape won't be symmetrical.

Therefore the correct option is (c)
