use the following information to answer the next question. substance boiling point ch₃oh 65 °c ch₃f -78 °c 11. the reason why the boiling point of ch₃f is so much lower than ch₃oh is due to which intermolecular forces? dipole - dipole only ldf only h - bonding only ldf and h - bonding

Answer

Brief Explanations:

$CH_3OH$ has hydrogen - bonding due to the presence of the $-OH$ group. Hydrogen - bonding is a strong intermolecular force. $CH_3F$ has dipole - dipole forces and London dispersion forces (LDF). LDF are present in all molecules, and $CH_3F$ is polar so it has dipole - dipole forces. But dipole - dipole and LDF in $CH_3F$ are weaker than the hydrogen - bonding in $CH_3OH$, which is why $CH_3F$ has a lower boiling point.

Answer:

Dipole - Dipole only, LDF only
