Question

what is the action of I2 and Naoh on Ethanol​

Answer 1

Answer: NaOH + C2H5OH = C2H5ONa + H2

Tri-iodo-methane (Iodoform)

Explanation:

Ethanol,C2H5OH, is an alcohol which reacts with sodium metal to yield sodium ethoxide,C2H5ONa, and a colorless gas which burns with a pop sound. Ethanol also reacts with iodine gas, I2 to form tri-iodo-methane commonly known as iodoform.

Answer 2

Yellow coloured iodoform is formed upon the action of I2 and NaOH on Ethanol​.

- The given reaction is known as the iodoform reaction.

- Ethanol is the only alcohol that gives this reaction.

- The complete balanced chemical reaction for the iodoform reaction of ethanol is given as follows:

C2H5OH + 4 I2 + NaOH → CHI3 + HCOONa + 5 HI

- CHI3 is yellow in colour and is known as iodoform.
