Question

The octet rule is not valid for the molecule (a) CO₂ (b) H₂O (c) O₂ (d) CO

Answer 1

Answer:

The octet rule is not valid for (d) CO.

Explanation:

Molecules having an odd number of electrons around them do not follow the octet rule. It is because the rule makes it mandatory to have eight electrons around each of the atoms.

In case of CO, the carbon atom can share at most two electrons from the oxygen atom, therefore a total of 6 valence electrons are present in its outermost shell. So, only the octet of oxygen atom is achieved. Hence, it does not obey the octet rule completely.

Answer 2

Hi
