Question

Which of the following is true in case of structural isomerism?

• A. Same molecular formula
• B. Same molecular weight
• C. Same properties
• D. Different structural formula

Answer 1

Answer: (A), (B), (D)

The correct options are
A

Same molecular formula

B

Same molecular weight

D

Different structural formula

Constitutional or structural isomerism

Without referring to space, the isomers differ in the arrangement of atoms within the molecule is called structural isomerism.
Thus structural isomers have:

Same empirical formula

Same molecular weight

Different properties

Different structural formula
