MCAT Question of the Day


  • Q:

    Carboxyl groups have higher boiling points than acid halides because they are capable of self-associating with hydrogen bonds to form dimeric associations. Acid halides, however, are only capable of receiving hydrogen bonds, not donating them, and cannot self-associate with hydrogen bonds. The structure on acid halides and carboxylic acids that receives hydrogen bonds is the:

     

    A

    carbon of the carbonyl group

    B

    oxygen of the carbonyl group

    C

    oxygen of the hydroxyl group

    D

    carbon of the R-group
