Answer» Solution :Due to MUCH stronger H-bonds in carboxylic acids than in alcohols, the boilig points of carboxylic acids are much higher than the boiling points of the corresponding alcohols. HOWEVER, due to absence of H-bonding in ethers, the boiling points of ethers are much lower than alcohols and carboxylic acids of cojmparable molecular masses. THUS, the boiling DECREASES in the order: `CH_(3)CH_(2)CH_(2)COOH gt CH_(3) CH_(2)CH_(2)CH_(2)OH gt CH_(3)CH_(2)OCH_(2) CH_(3)`. |
