2. What is the name of this compound?

[tex]\[ CH_3-CH_2-CH_2-CH_2-O-C_6H_5 \][/tex]

A. phenylbutyl ether
B. butylcyclohexyl ether
C. butylphenyl ether
D. cyclohexylbutyl ether



Answer :

To determine the name of the given compound, let's break down its structure step-by-step and analyze it systematically.

1. Identify the Components:
- The structure can be written as:
[tex]\[ CH_3 - CH_2 - CH_2 - CH_2 - O - C_6H_5 \][/tex]
- Here, we see two primary parts:
- The [tex]\(CH_3 - CH_2 - CH_2 - CH_2\)[/tex] group, which is a butyl group.
- The [tex]\(O - C_6H_5\)[/tex] group, which is a phenoxy group. [tex]\(C_6H_5\)[/tex] represents a phenyl ring attached to the oxygen atom.

2. Naming the Components:
- The [tex]\(CH_3 - CH_2 - CH_2 - CH_2\)[/tex] (butyl group) is attached to the oxygen atom, indicating it is an ether.
- The phenoxy group ([tex]\(O - C_6H_5\)[/tex]) is linked with the butyl group.

3. Determine the Naming Convention:
- Ethers are generally named by identifying the two groups attached to the oxygen atom and then adding the word "ether".
- In this case, the two groups are butyl and phenyl.

By considering all the components and their arrangements, the name of the compound is butylphenyl ether.
