Question

In which are the bonds ranked in order from smallest to greatest
A. N-N < N=N < N=N
B. N-P < N-N < N-O
C. Si-C < Si-N < Si-O
D. C-H < O-H < N-H

Answer 1

Option C is the correct answer.

The bonds are ranked from SiC to SiO (smallest to greatest) because moving from SiC to SiO, the polarity of the bond increases due to an increase in the electronegativity difference between the two atoms involved.
