The boiling points of carboxylic acids are higher than the comparable molecular masses of aldehydes, ketones, and alcohols. The hydrogen bond formed by the carboxylic acids are stronger than those in alcohols because O−H bond in C OOH is more strongly polarised due to the presence of electron withdrawing carboxy group in adjacent position then the O−H bonds of alcohols. What common use is made of sodium propionate and sodium benzoate?
Answer.
salicylic acid.
carboxylic acids with the presence of -COOH groups are capable of hydrogen bonding between molecules and more energy is necessary to overcome this additional intermolecular bonding, hence, the melting and boiling points for carboxylic acids are generally higher.
