Question

13 of 20
the table shows the normal boiling point of four compounds. which compounds have strongest intermolecular forces?

compound	normal boiling point (°c)
ch₃cl(ℓ)	-24.2
ch₃f(ℓ)	-78.6
hcl(ℓ)	-83.7

a ch₃f (l)
b ch₃cl (l)
c hcl (l)
d hf (l)

Explanation:

Step1: Recall the relationship

Stronger intermolecular forces require more energy to break, resulting in a higher boiling - point.

Step2: Compare boiling points

Among the given compounds, HF(ℓ) has the highest boiling point of 19.4 °C.

Answer:

D. HF (l)
