Question

How +ve charge on more electronegative elements is stable when extra bond is formed?

Answer 1

Hey mate this may help you

Rules for estimating stability of resonance structures:

• The greater the number of covalent bonds, the greater the stability since more atoms will have complete octets
• The structure with the least number of formal charges is more stable
• The structure with the least separation of formal charges is more stable
• A structure with a negative charge on the more electronegative atom will be more stable
• Positive charges on the least electronegative atom (most electropositive) is more stable
• Resonance forms that are equivalent have no difference in stability and contribute equally. (eg. benzene)
