Question

Write the mechanism for the reactions of
1) (E)-3-hexene and bromine and
2) (Z)-3-hexene and bromine in dichloromethane.
Assign R,S configuration for each of the products and determine whether they are related as enantiomers or identical.

I know how to write the mechanism for #1, but is it similar for #2? Does the reaction in dichloromethane make any difference?

Also I'm not sure about R,S configuration. I'm thinking each set of products in #1 and #2 are enantiomers. And then between #1 and #2, they are diastereomers. Please help verify my thinking.

THANK YOU!! :)
