PLEASE ANSWER ALL QUESTIONS
Question 5 The reaction below occurs via SN2 and E2 reaction mechanisms. The question only requires you to address the E2 reaction only. For the E2 reaction: Use Newman projections to show the relationship between the leaving group and the beta-hydrogen on the carbon labeled with the asterisk ("). 1. If the leaving group and the beta-hydrogen on the carbon labeled with the asterisk (1) are not in the correct orientation, show the result of the...
