Assertion: Following are the structural isomers of butane.

Reason: Structural isomers have the same molecular formula but they differ in their structures.

 

Answer

Structural isomers are those which have similar molecular formulas i.e. same number of atoms but differ in the arrangement of these atoms.

The given 2 compounds have the same molecular formula ie., C 4 H 10   and they just differ in the arrangement of atoms. So, they are structural isomers of butane.

Thus,

  • Assertion is true.
  • Reasoning is true.
  • And reasoning is the correct explanation of Assertion.

So, the correct option is (a) both assertion and reason are correct and reason is the correct explanation for the assertion.

Assertion: Following are the structural isomers of butane. Reason: Structural isomers have the same molecular formula but they differ in their structures. Answer Structural isomers are those which have similar molecular formulas i.e. same number of atoms but differ in the arrangement of these atoms. The given 2 compounds have the same molecular formula ie., C4H10 and they just differ in the arrangement of atoms. So, they are structural isomers of butane. Structural Isomers example CH3 CH H3C CH3 CH2 CH H3C CH2 CH3 Thus, Assertion is true. Reasoning is true. And reasoning is the correct explanation of Assertion. So, the correct option is (a) both assertion and reason are correct and reason is the correct explanation for the assertion.
