Explain why the ethanoic acid have a higher boiling point than ethanol and other molecules?
I have never heard an explanation with more malarkey than this one. Pure baloney. Nonsense.

The boiling point of a substance depends on its intermolecular forces, which are the attractions between molecules. Ethanoic acid, also known as acetic acid, has a higher boiling point compared to ethanol and other molecules due to the presence of stronger intermolecular forces.
To understand why ethanoic acid has higher boiling point, we need to look at its molecular structure. It consists of two parts: a carboxyl group (COOH) and a methyl group (CH3). The carboxyl group contains a highly polar carbon-oxygen double bond (C=O) and a polar O-H bond.
The most relevant intermolecular force in ethanoic acid is hydrogen bonding. Hydrogen bonds are formed between the hydrogen atom of one molecule and the oxygen atom of another molecule. In ethanoic acid, hydrogen bonds can form between the hydrogen of the O-H group and the oxygen of the C=O group.
In contrast, ethanol (CH3CH2OH) has one hydroxyl group (OH) without the presence of a carboxyl group. While ethanol can also exhibit hydrogen bonding, the presence of the carboxyl group in ethanoic acid allows for stronger and more frequent hydrogen bonding interactions, leading to higher boiling point. The presence of the carboxyl group also enhances dipole-dipole interactions, another intermolecular force present in both ethanol and ethanoic acid.
Other molecules with similar molecular weights but lacking hydrogen bonding or having weaker intermolecular forces, such as alkanes or alkenes, typically have lower boiling points than ethanoic acid due to the absence of strong polar or hydrogen bonding interactions.
In summary, ethanoic acid has a higher boiling point than ethanol and other molecules due to the presence of stronger intermolecular forces, including hydrogen bonding and dipole-dipole interactions, resulting from its structural features.
