Markownikoff's rule is best applicable to the reaction between

Correct answer: D. C3H6 + HBr

  • A. C3H6 + Br2
  • B. C2H4 + HCl
  • C. C3H8 + Br2
  • D. C3H6 + HBr

Explanation

Markovnikov's rule states that for a hydrogen halide being added to an asymmetric alkene, the hydrogen attaches itself to the carbon having more hydrogens whereas the halide binds to the carbon with the least hydrogens out of the two carbons formerly having a double bond. Option D is best suitable to display Markovnikov's rule as we have an asymmetric alkene and hydrogen bromide undergoing electrophilic addition.

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.
