Which of the following reactions will give 2,2-dibromopropane as its product?
Answer & explanation
Correct answer: option 3
Preparation of 2,2-dibromopropane takes place according to Markownikoff's rule using propyne and hydrogen bromide.
Step 1:Electrophilic addition of H+
CH3-C≡CH + HBr -----> CH3-C(Br)=CH2
Step 2:
CH3-C(Br)=CH2 + HBr -----> CH3-C(Br)2-CH3
