Question

Ethyl alcohol can be distinguished from n-propyl alcohol by using:

• A. Lucas reagent
• B. $I_2+NaOH$
• C. Na metal
• D. Bosches reagent

Answer 1

Answer: (B)

$I_2+NaOH$

Ethanol and 1-propanol can be distinguished with the help of the iodoform test. Because both give iodoform reaction.

The haloform reaction is a chemical reaction where a haloform ($CH{X}_3$, where X is a halogen) is produced by the exhaustive halogenation of a compound containing three alpha hydrogen atoms in the presence of a base.

R may be alkyl or aryl. The reaction can be used to transform acetyl groups into carboxyl groups or to produce chloroform ($CHC{l}_3$), bromoform ($CHB{r}_3$), or iodoform ($CH{I}_3$).
