Question

What is the action of cold hi on ethyl methyl ether?

Answer 1

✴Hii dear✴


# a) When hot hydrogen iodide is reacted with ethyl methyl ether, we get ethyl iodide, methyl iodide and water.

C2H5-O-CH3 + 2HI ---> C2H5I + CH3I + H2O


# b) Classification of Phenols-

Depending on the number of hydroxyl groups attached, we can classify phenols into three main types:


1)Monohydric phenols: These phenols contain one -OH group.

Example-

Phenol(Benzenol)

p-cresol(4-methylphenol)


2)Dihydric phenols: They contain two -OH groups. They could be either ortho-, meta- or para- derivative.

Example-

Catechol(Benzene-1,2-diol)

Resorcinol(Benzene-1,3-diol)


3)Trihydric phenols: They contain three -OH groups.

Example-

Benzene-1,3,5-triol
