Question

CORRECT order of stability for the following is $\mathrm{CH}_2=\mathrm{CH}^{-}, \mathrm{CH}_3-\mathrm{CH}_2^{-}, \mathrm{CH} \equiv \mathrm{C}^{-}$

Select the correct option:

$\mathrm{CH}_3-\mathrm{CH}_2^{-}>\mathrm{CH}_2=\mathrm{CH}^{-}>\mathrm{CH} \equiv \mathrm{C}^{-}$

$\mathrm{CH}_2=\mathrm{CH}^{-}>\mathrm{CH} \equiv \mathrm{C}^{-}>\mathrm{CH}_3-\mathrm{CH}_2^{-}$

$\mathrm{CH} \equiv \mathrm{C}^{-}>\mathrm{CH}_2=\mathrm{CH}^{-}>\mathrm{CH}_3-\mathrm{CH}_2^{-}$

$\mathrm{CH} \equiv \mathrm{C}^{-}>\mathrm{CH}_3-\mathrm{CH}_2^{-}>\mathrm{CH}_2=\mathrm{CH}^{-}$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

CH₂ = C̄H CH₃ − C̄H₂ CH ≡ C̄ Stability ∝ %S Order of stability CH ≡ C̄ > CH₂ = C̄H > CH₃ − C̄H₂
