Correct Answer
C Bromoethane
D 1,1,2,2-Tetrabromoethane
Correct Answer

Option B is the correct answer.

Detailed Explanation

Ethanol heated with concentrated H2SO4 at 170°C produces ethylene (ethene) gas. When ethylene is treated with bromine in CCl4, it undergoes electrophilic addition to form 1,2-dibromoethane (BrCH2-CH2Br).

Hint

What alkene is formed from ethanol dehydration, and what is its bromination product?
