Addition of HX to an Alkene

Draw a structural formula for the product of each alkene addition reaction.

Strategy

Use Markovnikov’s rule to predict the structural formula the product of each reaction. In the addition of HI and HCl, H adds to the carbon of the double bond that already has the greater

(a) Markovnikov’s rule predicts that the hydrogen of HI adds to carbon 1 and iodine adds to carbon 2 to give 2-iodo-2-methylpropane.

(b) H adds to carbon 2 of the ring and Cl adds to carbon 1 to give 1-chloro-1-methylcyclopentane.
