1) please provide iupac (systematic) names for the following: a. b. c.

Explanation:

Step1: Identify longest carbon - chain for a

The longest carbon - chain has 7 carbons (heptane). There are two methyl groups at positions 3 and 5.

Step2: Name compound a

The IUPAC name is 3,5 - dimethylheptane.

Step3: Identify parent ring and substituent for b

The parent ring is cyclohexane. There is a chloro - substituent and a methyl - substituent at the same carbon. The numbering starts from the carbon with the substituents.

Step4: Name compound b

The IUPAC name is 1 - chloro - 1 - methylcyclohexane.

Step5: Identify parent ring and substituents for c

The parent ring is cyclopentane. There are two methyl groups at positions 1 and 3.

Step6: Name compound c

The IUPAC name is 1,3 - dimethylcyclopentane.

Answer:

a. 3,5 - dimethylheptane b. 1 - chloro - 1 - methylcyclohexane c. 1,3 - dimethylcyclopentane
