Which one of the following compound does not have - OH group___________________?
Correct answer: D. ethyl acetate
- A. ethylene glycol
- B. glycerol
- C. picric acid
- D. ethyl acetate
Explanation
Ethyl acetate, CH3COOCH2CH3, is an ester and contains no hydroxyl, or -OH, group. Ethylene glycol has two -OH groups, glycerol has three, and picric acid has a phenolic -OH group. Students may choose picric acid because its name suggests an acid rather than an alcohol, but its structure still includes one hydroxyl group.
