Problem: Which resonance forms of silicon dioxide contribute the most to the actual bonding?a. A contributes the most. b. B contributes the most. c. C contributes the most. d. B and C contribute equally. e. A, B and C each contribute equally. f. It is impossible to say without more information.

FREE Expert Solution

We are provided with three resonance forms for SiO2 molecule and we have to determine which of the resonance forms contributes the most to the actual bonding.


The resonance form which contributes the most is the one which has:

  • Smallest possible formal charges on all atoms.
  • No positive formal charges on electronegative atoms when there are less electronegative atoms present.
