According to chad
.. with a secondary halide it's not so clear cut. For some secondary halides, the major product is the Anti-Zaitsev product while for other secondary halides it is the Zaitsev product. Ultimately for secondary halides it is difficult to formulate a steadfast rule. Nevertheless some professors and textbooks will oversimplify the situation and state that you always get the Anti-Zaitsev product when using a bulky base. It's not technically true but you will come across this teaching on a fairly regular basis. Sorry for the confusion. It's my sincere hope that you won't be asked this on the actual DAT or MCAT with all the confusion that surrounds this issue...

But in this case, there was no Hofmann product as an answer and the main purpose of the problem is to test the antiperiplanar so yeah
