Question

According to VSEPR theory, the most probable shape of the molecule having 4 electrons in the outershell of the central atom is:

• A. linear
• B. tetrahedral
• C. hexahedral
• D. octahedral

Answer 1

The correct option is B tetrahedral

When an atom has 4 electons in its outermost shell, it can share these electron with another atom to complete its octet and can form 4 $\sigma$ bonds. On sharing of these electrons, its steric number will be 4 and it will be $s{p}^3$ hybridised. Hence, its shape is tetrahedral eg.$C{H}_4$.
