I think electron withdrawing groups increase acidity, but I was wondering if benzene will be considered also an electron withdrawing group and increase acidity when it is present?

For Williamson ether synthesis, I know that primary and benzylhalides are prefered. I know that in general secondary halides are not prefered, but how can you choose an answer if several secondary halides are given? Like in question #1 subject test 3.

Any ideas?

Look closely, they wont give you a bunch of secondary ones...one of them is terciary..

FOr the first question, i doubt they will give you just benzene....and like putting an NH2 on the benzene will make it more basic tan benzene alone. but if they want most basic and they give you a bunch of ones with deactiviating groups, then benzene would be the best. I doubt they would make it that tricky

I should look more closely! I hope the questions aren't that tricky on the real thing.. Thanks!

I am not sure if you still need this info, but I saw the question you were taling about and if you look at choice C it is a tertiary. hope that helps
