Question

failure of octet rules​

Answer 1

Explanation:

1. Failure of octet rule: There are several stable molecules known in which the octet rule is violated i.e., atoms in these molecules have number of electrons in the valency shell either short of octet or more than octet.
2. BeF3, BF3, AlH3 are electron- deficients (octet incomplete) hence are Lewis acid.
