Answer

Step by step solution

01

Haloform reaction

The reaction occurs with the ketone in which halogenation occurs at the alpha carbon or the methyl carbon of ketone, and halogenation is occur three times from trihalomethane ketone, which is a best leaving group, then by proton transfer formation of acid occurs.

02

Reaction of 1phenylethanol + I2 excess

I2 is the oxidizing agent, and alcohol shows a positive test of iodoform, so iodine converts alcohol to ketone, which shows a haloform reaction to form tri halomethyl ketone followed by the proton transfer to form acid
