NEETChemistryGeneral Organic Chemistry
The false statements among the following are I. A primary carbocation is less stable than a tertiary carbocation. II. A secondary propyl carbocation is less stable than allyl carbocation. III. A tertiary free radical is more stable than a primary free radical. IV. Isopropyl carbanion is more stable than ethyl carbanion.
Options
- AI and II
- Band III
- CI and IV
- DII and IV
Correct answer
D. II and IV
Step-by-step solution
Since 2^ propyl carbocation is little more stable than allyl carbocation and ethyl carbanion is more stable than isopropyl carbanion.
