Chapter 26, Problem 71E

Interpretation Introduction

(a)

Interpretation:

Interpret the possible reaction of dihydrofuran according to given conditions.

Concept introduction:

Dihydrofuran is a monounsaturated derivative of furan with one double bond at 2 position. Hence it is also called as 2,5-dihydrofuran. It is an unsaturated compound hence it can decolorized the bromine water which is an addition reaction of bromine water with alkene (C=C) bond.

Interpretation Introduction

(b)

Interpretation:

Interpret the possible reaction of 3-methylbutanol according to given conditions.

Concept introduction:

A primary alcohol can be easily oxidized to respective aldehyde and further oxidation leads to the formation of carboxylic acid. Usually acidic potassium dichromate or potassium permanganate can be used as oxidizing agent for the oxidation of alcohols. Alcohols also react with sodium to sodium alkoxide and release hydrogen gas.

Interpretation Introduction

(c)

Interpretation:

Interpret the possible reaction of 3-methylpropanoic acid according to given conditions.

Concept introduction:

Carboxylic acid is highly oxidized species therefore it cannot oxidized further. All carboxylic acid molecules have −COOH group therefore they can give H+ ions and can react with basic compounds as well as with metals.
