The boiling points of amines are____than those of alcohols of comparable molecular mass due to_______

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Compounds**: We are comparing the boiling points of amines and alcohols that have comparable molecular masses. For example, consider ethylamine (C2H5NH2) and ethanol (C2H5OH). Both compounds have similar molecular weights due to the same number of carbon and hydrogen atoms.

2. **Hydrogen Bonding**: Both amines and alcohols can form hydrogen bonds. Hydrogen bonding occurs when a hydrogen atom is bonded to a highly electronegative atom (like nitrogen or oxygen) and is attracted to another electronegative atom.

3. **Electronegativity Comparison**: In alcohols, the electronegative atom is oxygen, while in amines, it is nitrogen. Oxygen is more electronegative than nitrogen, which means that the hydrogen bonds formed in alcohols are stronger than those formed in amines.
