13) Which of the following provides an efficient method of converting 3-bromo-2-methyl-1-butene into 2-methyl-2-butene?

A) 1) NaOH; 2) H2, Pd/C
B)   1) H2, Pd/C; 2) NaOEt
C) 1) H2, Pd/C; 2) Br2
E) 1) H2, Pd/C; 2) KOtBu

And I have already known that the correct answer is B, but why?

I cannot understand...Please help!!

Really thanks

Which is lower in potential energy: 2-methyl-2-butene or 2-methyl-1-butene? (circle one) I recently said that the answer was incorrect, that was a blunder on my part. I submitted the wrong answer when I made a comment. 2-methyl-butene is tert therefore has the highest stability and lowest PE

You will work as a group on this exercise. A sample of tert-butyl bromide (2-bromo-2-methyl propane) has been contaminated with some methyl bromide. The NMR spectrum of this sample shows two signals, one at 2.2 ppm and one at 1.8 ppm, corresponding to these two compounds respectively. The integrals of the two signals equate to 6:1 respectively. What is the mole percent of each compound in the mixture, or phrasing it another way, what percentage of the mixture is tert-butyl...
