Answer 1

Explanation:

Two or more compounds having the same molecular formula but different physical, chemical properties and struchtural formula are called isomers.

Thank you

Answer 2

Answer:

The correct option is (iii) Same molecular weight.

Explanation:

• Isomers are compounds with the same molecular weight but different structures, chemical properties, and functional groups.

• Isomers may have a different arrangement of atoms or groups in space.

• They show different behavior in presence of reagents or polarized light. Eg- optically active isomers.
• The functional groups are attached to the chain in different ways, making different types of compounds. Eg- dimethyl ether and ethanol.
• The molecular weight of the isomers of a substance must be the same because the number and the kind of atoms present are the same.  

Conclusion:

Isomers of a substance must same molecular weight.
