Question 22.7: Show the structure of ⓐ the three-carbon alcohol with an —OH...
Show the structure of
ⓐ the three-carbon alcohol with an —OH group at the end of the chain.
ⓑ the three-carbon carboxylic acid.
ⓒ the ester formed when these two compounds react.
ⓐ AND ⓑ
STRATEGY
1. Write the parent compound chain.
2. Put the functional group in the specified position.
3. Fill in the structural formula with H atoms.
ⓐ AND ⓑ
| C-C-C
C-C-C-OH CH_{3}-CH_{2}-CH_{2}-OH |
(a) 1. Parent compound chain
2. Functional group 3. Hydrogen atoms |
| C-C-C
C-C-\underset{\overset{||}{O} }{C} -OH
CH_{3}CH_{2}-\underset{\overset{||}{O} }{C}-OH |
(b) 1. Parent compound chain
2. Functional group 3. Hydrogen atoms |

Join the acid and the alcohol and remove OH from the functional group (COOH) of the acid and the H from the functional group (OH) of the alcohol.
CH_{3}CH_{2}CH_{2}-\xcancel{OH} \xcancel{HO}-\underset{\overset{||}{O} }{C}-CH_{2}CH_{3}
↓
CH_{3}CH_{2}CH_{2}-O-\underset{\overset{||}{O} }{C}-CH_{2}CH_{3}
