Question

Ethyl alcohol is heated with sodium carbonate and Iodine

Answer 1

Answer:

when ethyl alcohol is heated with sodium carbonate and iodine gives yellow coloured crystalline solid iodoform and this procedure is known as iodoform test.

Explanation:

Solution:

(iodoform)

CH3CH2OH + I2 + Na2CO3 ⟶ CHI3

(Ethanol) (yellow ppt.)+ HCOONa + Nal + H2O + CO2

Answer 2

When ethyl alcohol ( CH$_{3}$CH$_{2}$OH ) is heated with sodium carbonate ( Na$_{2}$CO$_{3}$ ) and iodine ( I$_{2}$ ) , iodoform is formed .

CH$_{3}$CH$_{2}$OH + I$_{2}$ + Na$_{2}$CO$_{3}$ ⟶ CHI$_{3}$ (pale yellow precipitate ) + HCOONa + Nal + H$_{2}$O + CO$_{2}$

• Iodoform ( CHI$_{3}$ ) is a pale yellow coloured crystalline solid .
• In this reaction, iodoform is formed of precipitate .
• This reaction is known as the iodoform test .
• The molar mass of CHI$_{3}$ is 393.73 g/mol .
