Question

The IUPAC name of the following compound is

• A. Bromoacetophenone
• B. 1-Bromophenylethanone
• C. 2-Bromo-1-phenylethanone
• D. 3-Bromo-1-phenylethanone

Answer 1

The correct option is C

2-Bromo-1-phenylethanone

As we know, when the benzene ring is named as a substituent on the other molecule, it is named as a phenyl group.

Now,

Ketone $\to -\stackrel{O}{\stackrel{||}{C}}-$ one (suffix)

Two carbon $\to Eth\left(wordroot\right)$

Therefore,

2-bromo-1-phenylethanone [Alphabetical order]
