Question

Which of the following substances has the lowest boiling point?

1) CH3CH2CH2F
2) CH3CH2CH3
3) CH3CH2CH2OH
4) CH3CH2CH2CH3

Answer 1

The compound with the lowest boiling point is CH3CH2CH2F.

Step-by-step explanation:

The boiling point of a substance depends on its intermolecular forces, which are determined by the molecular structure and polarity. In this case, we are comparing the boiling points of different compounds:

1. CH3CH2CH2F
2. CH3CH2CH3
3. CH3CH2CH2OH
4. CH3CH2CH2CH3

To determine the lowest boiling point, we need to consider the molecular size and polarity. Among the given options, the compound with the lowest boiling point is CH3CH2CH2F.

This is because it is the smallest molecule and has the weakest intermolecular forces.
