Question

Indicate whether each of the following pairs represents structural isomers or the same molecule:

a.

b.

c.

Short answer

(a) The given molecules i.e. are same molecules

(b) The given molecules i.e. are structural isomers

(c) The given molecules i.e. are structural isomers

Step-by-step solution

Part (a) Step 1: Given information

We need to find whether the given molecules i.e.structural isomers or the same molecule

Part (a) Step 2: Explanation

We know that

In the given pair of molecules, no. of atoms of elements are equal and Bond between them are also similar.

Therefore, the given molecules are same

Part (b) Step 1: Given information 

We need to find whether the given molecules i.e. structural isomers or the same molecule

Part (b) Step 2: Explanation

We know that

Structural isomers are those in which no. of atoms of each element are equal but the way of their bonding is different.

Therefore, the given molecules are structural isomers

Part (c) Step 1: Given information  

We need to find whether the given molecules i.e. structural isomers or the same molecule

Part (c) Step 2: Explanation 

We know that

Structural isomers are those in which no. of atoms of each element are equal but the way of their bonding is different.

Therefore, the given molecules are structural isomers
