2. Decreases its boiling point

3. Doesn’t change its boiling point

4. None of the above

The product obtained on the addition of HBr to propene in the absence and presence of benzoyl peroxide are respectively

1. 1-Bromopropane, 2-Bromopropane

2. 2-Bromopropane, 1-Bromopropane

3. 1-Bromopropanol, 2-Bromopropanone

4. 2-Bromopropanone, 1-Bromopropanol

Decreasing order of acidic behavior of benzene, n-hexane, and ethyne is -
