Question

The correct stability order of the given canonical structures is:

• A. I > II > III
• B. III > I > II
• C. I > III > II
• D. II > III > I

Answer 1

The correct option is C I > III > II

Compound I > III > II.

order of stability of canonical structures is followed by the following rules:

1. Neutral compounds are more stable than charged.

2. more the no. of pi bonds more is the stability.

3. stability is more when the atom has a complete octet.

compound (I) has a double bond, and oxygen which is more electronegative, with the incomplete octet, then in compound (III) the nitrogen is electronegative and has a positive charge and the octet is incomplete.
