Compound in which addition takes place through Markovnikov's rule is:

Correct answer: B. C𝐻3 βˆ’ 𝐢(𝐢𝐻3) = 𝐢𝐻 βˆ’ 𝐢𝐻3

  • A. C𝐻3 βˆ’ 𝐢𝐻 = 𝐢𝐻 βˆ’ 𝐢H3
  • B. C𝐻3 βˆ’ 𝐢(𝐢𝐻3) = 𝐢𝐻 βˆ’ 𝐢𝐻3
  • C. C2𝐻5 βˆ’ 𝐢𝐻 = 𝐢𝐻 βˆ’ 𝐢𝐻3
  • D. C𝐻3 βˆ’ 𝐢𝐻 = 𝐢𝐻 βˆ’ 𝐢3𝐻7

Explanation

Markovnikov Rule predicts the regiochemistry of HX addition to unsymmetrically substituted alkenes. The halide component of HX bonds preferentially at the more highly substituted carbon, whereas the hydrogen prefers the carbon which already contains more hydrogens.

About Alkyl Halides

Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
