Question
The correct stability order for the following species is
Options
A.(II) > (IV) > (I) > (III)
B.(I) > (II) > (III) > (IV)
C.(II) > (I) > (IV) > (III)
D.(I) > (III) > (II) > (IV)
Solution
(I)
Stabilizes by resonance and have six α - hydrogen atoms (hyperconjugation)
(II)
(III) Stabilizes by resonance and have only three α - hydrogen atoms.
have five α - hydrogen atoms.
(IV)
have only two α - hydrogen atoms.
∴ I > III > II > IV
Stabilizes by resonance and have six α - hydrogen atoms (hyperconjugation)
(II)
(III) Stabilizes by resonance and have only three α - hydrogen atoms.
have five α - hydrogen atoms.
(IV)
have only two α - hydrogen atoms.
∴ I > III > II > IV
