Question

What is the iupac name of PHCH2CH3?

Answer 1

Answer:

The IUPAC name of the compound PhCH₂CH₃ is Ethylbenzene.

Explanation:

The longest carbon chain of the compound is the benzene ring So it will be the parent chain and the alkyl group will be considered as a substitute. The alkyl group contains 2 C, so the root-word of substituent becomes 'Eth'. Since there is only one substituent attached to the parent chain numbering starts from that C.

then the name of the compound is 1-Ethylbenzene. We can omit 1.

Hence, the IUPAC name of PhCH₂CH₃ is Ethylbenzene.
