MCQ
The correct order of increasing bond length of $C - H, C - O, C - C$ and $C=C$ is
- ✓$C - H < C=C < C - O < C - C$
- B$C - C < C=C < C - O < C - H$
- C$C - O < C - H < C - C < C = C$
- D$C - H < C - O < C - C < C=C$
${C=C: 0.134\; \mathrm{nm}}$
${C-O: 0.143\; \mathrm{nm}}$
${C-C: 0.154 \;\mathrm{nm}}$
Bond length order is
$C-H < C=C < C-O < C-C$
