Answer:
Correct Answer: 7. (d)
Solution:
- Carbon $(C)$ has greatest ability to form stable $p \pi-p \pi$ multiple bonds. $2 p$-orbitals of this element participate in the process. The stability of multiple bonds of $C$ is attributed to their closeness with $C$-nucleus. Thus, the smaller size of $C$ plays a significant role in the process.
