Which of the following is the correct structure for the compound with the common name phenyl propyl ether?

• A. A benzene ring bonded through an oxygen atom to a methyl group ($C{6}_{H}5$-O-$C{1}_{H}3$)
• B. A benzene ring bonded through an oxygen atom to an ethyl group ($C{6}_{H}5$-O-$C{2}_{H}5$)
• C. A propyl group bonded through an oxygen atom to another propyl group ($C{3}_{H}7$-O-$C{3}_{H}7$)
• D. A benzene ring bonded through an oxygen atom to a propyl group ($C{6}_{H}5$-O-$C{3}_{H}7$)

Answer: (D)

Verified step by step guidance

1. Understand the name 'phenyl propyl ether': 'phenyl' refers to a benzene ring (C\6H\5) attached as a substituent, and 'propyl' refers to a three-carbon alkyl group (C\3H\7).
2. Recall that ethers have the general structure R\-O\-R', where an oxygen atom connects two alkyl or aryl groups.
3. Identify the two groups connected by the oxygen in phenyl propyl ether: one side is the phenyl group (C\6H\5) and the other side is the propyl group (C\3H\7).
4. Compare the given options to find the structure where the oxygen atom links a benzene ring (phenyl) to a propyl group, which matches the name phenyl propyl ether.
5. Exclude options where the oxygen is bonded to methyl (C\1H\3), ethyl (C\2H\5), or another propyl group on both sides, as these do not correspond to the name phenyl propyl ether.
