It says that it would be an E2 reaction; however, I was thinking it would be an Sn2..

Hi Caleb,

I agree with your book on it being E2. SN2 works best with primary carbons, but here the carbon Br is attached to is a secondary carbon. Additionally you have a strong base that it not bulky, suggesting a Markovnikov product with a methyl shift to get 2,3-dimethyl-2-butene
