The addition of HBr to an unsymmetrical alkenes follows?
Correct answer: B. Markovnikov's addition
- A. Direct addition
- B. Markovnikov's addition
- C. Anti Markovnikov's addition
- D. Dehydration
Explanation
Since the alkene and the reagent (HBr) are both unsymmetrical markovnikov's rule will be followed. According to which the negative part of the reagent ( bromide ion) will attach to the carbon with fewer hydrogen atoms. Dehydration is when a water molecule is removed i.e., from alcohols to form alkenes.

About Alkenes
Alkenes are unsaturated hydrocarbons containing a carbon-carbon double bond with sigma and pi components and restricted rotation. Their reactions include electrophilic addition of hydrogen, halogens, hydrogen halides and water, with Markovnikov orientation, oxidation, combustion and polymerisation, while their preparation commonly involves elimination from alkyl halides or alcohols.
