The correct order of decreasing length of the bond as indicated by the arrow in the following structures is 
- A I>II>III
- B II>I>III
- C III>II>I
- D I>III>II
Answer & Solution
Correct Answer
(C) III>II>I
Step-by-step Solution
Detailed explanation
The length of carbon-carbon single bond is always greater than that of the carbon-carbon double bond. In III, positive charge is not in conjugation of double bond, so the bond does not acquire a double bond character. However, chances of acquiring double bond character fof the…
