To name a compound, general pattern which is used is:
Prefix + word-root + suffix
(a)
Answer to Problem 55A
3-Methylbutanoic acid
Explanation of Solution
The numbering is done from right side to give carboxylic group number 1. ‘oic acid’ suffix is used to indicate carboxylic group.
The chain contains four carbon atoms which are single bonded. So word-root ‘butan’ is used. ‘e’ is removed as per the rules.
The skeleton shows one methyl is attached at C-3. Therefore, name of compound is 3-Methylbutanoic acid

Answer to Problem 55A
2-Hydroxypropanoic acid
Explanation of Solution
The numbering is done from right side to give carboxylic group number 1. ‘oic acid’ suffix is used to indicate carboxylic group.
The chain contains three carbon atoms which are single bonded. So word-root ‘propan’ is used. ‘e’ is removed as per the rules.
The skeleton shows one hydroxyl is attached at C-2. Therefore, name of compound is2-Hydroxypropanoic acid

Answer to Problem 55A
3,4-Dimethylhexanoic acid
Explanation of Solution
The numbering is done from right side to give carboxylic group number 1. ‘oic acid’ suffix is used to indicate carboxylic group.
The chain contains six carbon atoms which are single bonded. So word-root ‘hexan’ is used. ‘e’ is removed as per the rules.
The skeleton shows two methyl groups are attached one at C-3 and other at C-4. Therefore, name of compound is 3,4-Dimethylhexanoic acid
