Answer

Explanation:

Step1: Identify intermolecular forces

$F_2$ is a non - polar molecule, has only London dispersion forces. $CO_2$ is non - polar, also has London dispersion forces, but larger molar mass than $F_2$, so stronger London forces. $NH_3$ has hydrogen bonding (due to N - H bonds) along with London dispersion forces, and hydrogen bonding is a stronger intermolecular force.

Step2: Compare strength

London dispersion forces increase with molar mass for non - polar molecules. $F_2$ has lower molar mass than $CO_2$, so $F_2$ has weaker London forces than $CO_2$. And hydrogen bonding in $NH_3$ makes its intermolecular forces stronger than both $F_2$ and $CO_2$.

Answer:

$F_2<CO_2 < NH_3$
