Question

complete the following reaction: CH3-CH=CH2+HBr gives

Answer 1

ch3-ch=ch2 + HBR = ch3-chBr-ch3

Answer 2

Answer: The product obtained is 2-bromopropane.

Explanation:

Whenever an unsymmetrical alkene is present with polar reagents like HX, then the negative part of the polar reagent adds to that carbon atom of double bond which has minimum number of hydrogen atoms and will form a halo-alkane. This rule is known as Markovnikov rule.

Hence, addition of hydrogen bromide to 1-propene will yield 2-bromopropane
