Question

I simply need help on these three questions. Thank you

Number 3 is asking for the mechanism but I believe there is a typo.

I'll have to do number 4 on my own.

Number 5 is asking for a mechanism.

3. Give the reagents/conditions and show the mechanism for the following reaction (15 pts) OH CH3 CH3 4. Dr. Goodchem is making an intermediate. He conducted the reactions below using the conditions given. Explain the rationale behind the methylation of the benzene ring. Explain why he got the product yields noted for the first reaction and the second reaction a. b. 1. nBuLi/TMEDA O Me Me Ph Ph Ph 2. Mel Ph Ph 90% 10% 1. S-BuLi/TMEDA O Me Me, Ph Ph 2. Mel Ph Ph Ph 36% 64% 0143100 88006 6
