The correct order of \(\mathrm{C}=\mathrm{O}\) bond length in ethyl propanoate (I), ethyl propenoate (II) and ethenyl propanoate (III) is
- A I \( > \) II \( > \) III
- B III \( > \) II \( > \) I
- C I \( > \) III \( > \) II
- D II \( > \) I \( > \) III
Answer & Solution
Correct Answer
(D) II \( > \) I \( > \) III
Step-by-step Solution
Detailed explanation
Hint : \(\mathrm{C}=\mathrm{O}\) bond length \(\text {II } > \text { I } > \text { III }\) bond has the most single bond character in compound II and the least single bond character in compound III.
