| Quote: | | Question 28 - I understand why the answer is A (I got my functional groups mixed up), but the way the categories are listed in the table, it makes it seem like 'monofunctional' applies to all of them, not just carboxylic acids, in which case, D would not apply either. |

| Quote: | | 28: The benefit of doing lots of problems is pattern recognition. The setup of this table is very very common for both organic chemistry in general and the MCAT specifically. It is better to misinterpret in the comfort of your own home than on the real thing! Monofunctional only refers to the group which immediately follows that designation. |

| Adding to the confusion, group I lists "polyfunctional compounds with hydrophilic groups." |

| Can you please elaborate on the mono vs poly functional group used for the MCAT? Choice D seems to be a polyfunctional compound consisting of two hydrophilic groups: enol (or ketone depending on equilibrium) and an alcohol. How does the definition allow for this compound to be monofunctional? |

Amen, another terrible question, both A and D are reasonable choices. The group I can contain "polyfunctional compounds with hydrophillic groups"
I think that a compound with a double bond, and two hydroxyls would definitely qualify |
