MCQ
Bromination of an alkane as compared to chlorination proceeds _____________.
- AAt a slower rate
- BAt a faster rate
- CWith equal rate
- DWith equal rate (or) different rate depending upon the temperature.
✓
Answer
- At a slower rate
Explanation:
Bromination of an alkane occurs at a slower rate than chlorination of an alkane.
As we know that halogenation involves the formation of a carbon-halogen bond. Now, the ease of halogenation will certainly depend on the carbon-halogen bond strength.
Bond formation energy of C−Cl is higher than that of C−Br bond.
So, the ease of bromination is lower than the ease of chlorination.
