Question

1. draw the structure of the alcohol, carboxylic acid and ester needed to make the following flavours.

make sure you draw all of the chemical bonds in the molecule.
cherry
structure of alcohol structure of carboxylic acid
structure of ester

Explanation:

Cherry flavor is commonly associated with ethyl benzoate, an ester formed by the condensation of ethanol (alcohol) and benzoic acid (carboxylic acid). All structures show full chemical bonds.

Answer:

Structure of alcohol (Ethanol):

      H   H
      |   |
H — C — C — O — H
      |   |
      H   H

Structure of carboxylic acid (Benzoic acid):

      O
      ||
H — O — C — C₆H₅
(where C₆H₅ is the benzene ring:
      H
      |
H — C — C — H
    \   /
     C C
    /   \
H — C — C — H
      |
      H
with the carboxylic acid group attached to one carbon of the ring)

Structure of ester (Ethyl benzoate):

      O
      ||
H₅C₆ — C — O — C₂H₅
(where C₆H₅ is the benzene ring as above, and C₂H₅ is the ethyl group: H₃C-CH₂-)

Expanded full-bond structure of ethyl benzoate:

      H   H
      |   |
H — C — C — O — C — C₆H₅
      |   |       ||
      H   H       O
(benzene ring structure as shown for benzoic acid)
