Compound X has been investigated for use as an artificial sweetener. [Figure of compound X, a glucose derivative with two -Cl and multiple -OH groups] The two C-Cl bonds can be hydrolysed by hot NaOH(aq). The C-O-C bonds cannot be hydrolysed by hot NaOH(aq). What are the numbers of specified types of –OH groups before and after hydrolysing the two C-Cl bonds?

Abefore hydrolysis: secondary: 0, primary: 1, after hydrolysis: secondary: 2, tertiary: 4
Bbefore hydrolysis: secondary: 0, primary: 2, after hydrolysis: secondary: 1, tertiary: 4
Cbefore hydrolysis: secondary: 4, primary: 1, after hydrolysis: secondary: 5, tertiary: 1
Dbefore hydrolysis: secondary: 4, primary: 2, after hydrolysis: secondary: 4, tertiary: 1
✓ Correct answer
C: before hydrolysis: secondary: 4, primary: 1, after hydrolysis: secondary: 5, tertiary: 1
