Is benzoic acid soluble in diethyl ether?
Answers: Benzoic acid is more soluble in diethyl ether than water. So benzoic acid would be in the organic layer. Benzoic acid is more soluble in ether because the benzene ring is nonpolar, aye. Benzoate salts are water soluble, though, because water is better able to stabilize the negative charge on the oxygen.
How do you remove O-benzyl ether protective groups?
Benzyl ether protective groups are oxidatively removed by ozone under relatively mild conditions. Reaction products are benzoic ester, benzoic acid, and the corresponding alcohol. Subsequent deacylation with sodium methoxide affords a convenient debenzylation technique which has been applied to various O -benzyl protected carbohydrates.
