b.2-propanol

c. hexanal

Short Answer

Expert verified

(a) The 1-propanolwill not give a positive Tollens test.

(b) The 2-propanolwill not give a positive Tollens test.

(c) The hexanal will give a positive Tollens test.

Step by step solution

01

Part (a) Step 1 : Given information 

We need to find that whether the 1-propanolwill give tollens test or not

02

Part (a) Step 2: Explanation

We know that

Tollens test is given by aldehydes.

And as the given compound is alcohol

Therefore,

The given compound will not give Tollens test.

03

Part (b) Step 1 : Given information 

We need to find that whether the 2-propanolwill give tollens test or not

04

Part (b) Step 2: Explanation 

We know that

Tollens test is given by aldehydes.

And as the given compound is alcohol

Therefore,

The given compound will not give Tollens test.

05

Part (c) Step 1 : Given information  

We need to find that whether the hexanal will give tollens test or not

06

Part (c) Step 2: Explanation 

We know that

Tollens test is given by aldehydes.

And as the given compound is an aldehyde

Therefore,

The given compound will give Tollens test.
