Addition of HCl to propene forms _?
Correct answer: B. 2-chloropropane
- A. 1-chloropropane
- B. 2-chloropropane
- C. 3-chloropropane
- D. None pf the above
Explanation
HCl reacts with propene in an electrophilic addition reaction. According to Markovnikov's rule, the H (of HCl) bonds to the carbon which already has more hydrogens present. Hence, the correct option is (B).

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.
