Why boiling point of carboxylic acid is more than that of alcohols?

Carboxylic acids have a high boiling point because of their ability to form intermolecular hydrogen bonds. Hydrogen bonds formed in carboxylic acids are stronger than those in alcohols. The –OH bond in –COOH is more strongly polarised than the –OH bond of alcohols.

Why do carboxylic acids boil higher temperatures than do alcohols ketones or aldehydes of similar molar masses?

Carboxylic acids boil at considerably higher temperatures than do alcohols, ketones, or aldehydes of similar molecular weights. This is because they: A) have a greater oxygen content. Why are the OH groups of carboxylic acids more acidic than alcohols?

Why do carboxylic acids have a higher boiling point than ketones?

Due to formation of intermolecular H -bonding in carboxylic acid, association occurs. Hence boiling point increases and become more than the boiling point of aldehydes, ketones and alcohols of comparable molecular masses.

Why do aldehydes have lower boiling point than alcohols and carboxylic acids?

In the carboxylic acids, the carboxyl group are involved in the intermolecular hydrogen bonding. Therefore, aldehydes and ketones have lower boiling points than the corresponding acids of comparable molecular mass.

Why does carboxylic acid has a higher boiling point?

Carboxylic acids exhibit strong hydrogen bonding between molecules. They therefore have high boiling points compared to other substances of comparable molar mass. The carboxyl group readily engages in hydrogen bonding with water molecules (Figure 15.3. 1).

Why are carboxylic acids more acidic than alcohols and phenols?

Answer : Carboxylic acids are more acidic than alcohols or phenols, although all of them have a hydrogen atom attached to an oxygen atom (—O—H) because the conjugate base of carboxylic acids or the carboxylate ion is stabilized by resonance. Thus, carboxylic acids can release proton easier than alcohols or phenols.

Why are carboxylic acids more polar than alcohols?

Carboxylic acids are more polar than alcohols because there are two oxygen atoms present in a carboxylic acid molecule.

Does carboxylic acid have a higher boiling point than ketone?

Carboxylic acids have higher boiling points than aldehydes, ketones and even alcohols of comparable molecular mass.

Why do alcohols have higher boiling points than aldehydes?

In alcohols hydrogen bonding exists and hence has a greater boiling point than aldehyde and ketone. So the overall molecular mass for a single molecule increases and hence the boiling point increases.

Why Is carboxylic acid more acidic than alcohol and phenol?

Carboxylic acids dissociate in water to form carboxylate ion and the hydronium ion. The carboxylate ion formed is stabilized through resonance by effective delocalization of the negative charge. Hence, the carboxylic acids are more acidic than phenols.

Why are the boiling points of carboxylic acids higher than alcohols?

The boiling points of carboxylic acids are higher than the corresponding alcohols because Carboxylic acids have a high boiling point because of their ability to form intermolecular hydrogen bonds. Hydrogen bonds formed in carboxylic acids are stronger than those in alcohols.

Why are carboxilic acids more stable than ionic acids?

Intermolecular forces are the reason. Carboxilic acids have capability of forming a dimer by hydrogen bonding. That enables a very stable arrangement. Alcohol arranges about the oxygen primarily by hydrogen bonding.

Why are carboxylic acids soluble in water?

Carboxylic acids are more soluble in water than alcohols, ethers, aldehydes, and ketones of comparable molecular weight. They form hydrogen bonds with water molecules through both their C=O. and OH groups. Alcohols are soluble in water.

What is the relationship between molecular mass and boiling point?

The higher the molecular mass the higher the boiling point. This relates to the Van der Waals dispersion forces: the larger (~molecular mass) the molecule the higher the surface area hence more Van der Waals interactions.
