Options
- A. But-2-ene
- B. Hex-3-ene
- C. Ethene
- D. 2-methyl propene
Answer
D. 2-methyl propene
Step-by-step solution
Markovnikov's rule is applicable for the addition of unsymmetrical reagents to unsymmetrical alkenes. But-2-ene (CH_3-CH=CH-CH_3) is a symmetrical alkene. Hex-3-ene (CH_3-CH_2-CH=CH-CH_2-CH_3) is a symmetrical alkene. Ethene (CH_2=CH_2) is a symmetrical alkene. 2-methylpropene (CH_3-C(CH_3)=CH_2) is an unsymmetrical alkene. Therefore, 2-methylpropene will undergo addition of HBr according to Markovnikov's rule.
