Question

I need help with problems with 5 and 6. I'm not sure how to do them. Thanks!

5. the stability of carbocations is generally explained by a concept known as hyperconjugation. Use this concept to explain why a primary (1°) carbocation is more stable than a methyl (CH3+) carbocation. You must use a simple and concise drawing to show your point.

6. Using frontier orbital theory, explain why an E2 reaction must have the beta-hydrogen and the leaving group anti-periplanar to each other.
