write the systematic name of each organic molecule:\n| structure | name |\n|--|--|
Answer
Explanation:
Step1: Identify the longest carbon - chain with the carboxyl group
For the first molecule, the longest carbon - chain with the carboxyl group ($-COOH$) has 5 carbons. The carboxyl carbon is carbon - 1. There is a methyl group at carbon - 2, a hydroxyl group at carbon - 3, and a hydroxyl group at the end of the chain.
Step2: Name the molecule
The name is 2 - methyl - 3,5 - dihydroxypentanoic acid.
Step3: For the second molecule
The longest carbon - chain with the carboxyl group has 6 carbons. The carboxyl carbon is carbon - 1. There is a chlorine atom at carbon - 3, and two methyl groups at carbon - 2 and carbon - 4.
Step4: Name the molecule
The name is 3 - chloro - 2,4 - dimethylhexanoic acid.
Step5: For the third molecule
The longest carbon - chain with the carboxyl group has 4 carbons. The carboxyl carbon is carbon - 1. There are two methyl groups at carbon - 3.
Step6: Name the molecule
The name is 3,3 - dimethylbutanoic acid.
Answer:
- 2 - methyl - 3,5 - dihydroxypentanoic acid
- 3 - chloro - 2,4 - dimethylhexanoic acid
- 3,3 - dimethylbutanoic acid
