How many stereoisomers can you obtain from any type of bromination (not just the one we performed in the lab) on the (E)-stilbene (count all possible stereoisomers, not only the ones that you obtained today)

the answer is barium and copper bromide

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
