Question

with the help of chemical test distinguish between Ethyl bromide and bromobenzene

Answer 1

Bromoethane on reaction with KOH/NaOH in water/ethanol will give ethanol, while bromobenzene will give phenol.


Ethyl bromide and Bromobenzene

EthylBromide + aq KOH + dil HNO3 + AgNO3 → Yellow precipitate

Bromobenzene + aq KOH + dil HNO3 + AgNO3 → No Yellow precipitate

Answer 2

Hey dear,

● Answer -
Iodoform test


● Explaination -
# Ethyl bromide -
Ethyl bromide on reaction with NaOH gives ethanol.
C2H5Br + NaOH ---> C2H5OH + NaBr

Ethyl alcohol on iodoform test gives yellow precipitate.
C2H5OH + NaOI ---> CHI3 + HCOONa

# Bromobenzene -
Bromobenzene on reaction with NaOH gives phenol.
C6H5Br + NaOH ---> C6H5OH + NaBr

Phenol gives negative iodoform test. i.e. no precipitation.

Hope this helped you...
