Electrophilic Addition HBr with Propene

Postby Alex Nguyen 3I » Thu Mar 03, 2016 7:31 pm

In the reaction, a double bond between the 1st and 2nd carbon is attacking the hydrogen. In the book, the H from HBr bonds to the first carbon in propene, and the bromide eventually bonds to the 2nd carbon prdocuging 2-Bromopropane as the final product. Could you/should you bond the bromide with the first carbon so that it would be (1)-Bromopropane?

Under a certain catalytic condition, you can. However, normally Br will attach to the higher order C (secondary over primary in this case) because it stabilize the cation better.
