Shown below is the structure of methyl acetate with three different \(\alpha\), \(\beta\) and \(\gamma\) carbon - oxygen bonds.
The correct order of bond lengths of these bonds is :
- A \(\alpha > \beta > \gamma\)
- B \(\alpha < \beta < \gamma\)
- C \(\alpha = \beta = \gamma\)
- D \(\alpha < \beta = \gamma\)
Answer & Solution
Correct Answer
(B) \(\alpha < \beta < \gamma\)
Step-by-step Solution
Detailed explanation
In methyl acetate, the \(\alpha\) bond is a \(C=O\) double bond, which is the shortest among the three. The \(\beta\) bond is a \(C-O\) single bond adjacent to a carbonyl group. Due to resonance (\(CH_3-C(=O)-O-CH_3 \leftrightarrow CH_3-C(-O^-)=O^+-CH_3\)), the \(\beta\) bond…
