Question

question 5 (1 point)
name the following compound.

a) 4 - methyl - 3 - propylhexene
b) 3 - propyl - 4 - methylhexane
c) 4 - ethyl - 3 - methylheptane
d) 4 - ethyl - 3 - methylhexene
e) 4 - methyl - 3 - propylhexane

Explanation:

Step1: Determine the parent chain

The longest carbon - chain has 7 carbon atoms. So, the parent chain is heptane (since it is an alkane, no double bonds).

Step2: Identify the substituents

There is a methyl group ($-CH_3$) on the 3rd carbon and an ethyl group ($-CH_2CH_3$) on the 4th carbon.

Step3: Name the compound

When naming, we list the substituents in alphabetical order. So, it is 4 - ethyl - 3 - methylheptane.

Answer:

C. 4 - ethyl - 3 - methylheptane
