According to this question, esters and amides are insoluble in HCl and NaOH. Weren't they hydrolysed when either was added to them?
For e.g lets look at structure E. The mark scheme to biii says it contains amide and alchohol functional groups. Yet table 1 says it's insoluble in HCl. Won't the amide be hydrolysed when HCl is added to it? Doesn't that qualify E as being soluble in it? Thanks!
