Organic Chemistry: Some Basic Principles and Techniques

A tertiary-butyl carbocation is more stable than a secondary-butyl carbocation because of:

  1. A.The −I-I effect of −CH3-\mathrm{CH_3} groups
  2. B.The +R+R effect of −CH3-\mathrm{CH_3} groups
  3. C.The −R-R effect of −CH3-\mathrm{CH_3} groups
  4. D.Hyperconjugation✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
