Question

Which one can differentiate between C2 h5 0h and Ch3oh

Answer 1

Answer:

Explanation:

Answer 2

Answer:

To distinguish the ethanol CH₃CH₂OH  from methanol CH₃OH, iodoform test is being used.

Explanation:

Iodoform test can be performed only on the alcohols having alpha methyl group. The ethanol has methyl group at alpha position but methanol does not have any methyl group at alpha position.  

The reagent for the iodoform test is I₂ and NaOH.

  $CH_{3}CH_{2}OH+I_{2}+NaOH$    →   $CHI_{3}+HCOONa$

Where $CHI_{3}$ is iodoform.

    $CH_{3}OH+I_{2}+NaOH$   →    No reaction

Therefore iodoform test can be useful to distinguish both types of alcohols.
