JEE Main 2026 — 6 April, Evening Shift — Question 57

Shown below is the structure of methyl acetate with three different α,β\alpha, \beta and γ\gamma carbon-oxygen bonds.

figure

The correct order of bond length of these bonds is :

  1. Option A:

    α>β>γ\alpha>\beta>\gamma

  2. Option B:

    α<β<γ\alpha<\beta<\gamma

    Correct
  3. Option C:

    α=β=γ\alpha=\beta=\gamma

  4. Option D:

    α<β=γ\alpha<\beta=\gamma

Answer: B

Step-by-step solution

R.Hybrid

RS 1 is more stable than RS 2 ∴ contribution of RS1 is more than RS2 in it's R.H. ∴ Order of bond length α<β<γ\alpha<\beta<\gamma
