Given below are two statements, one is labelled as
Assertion A and the other is labelled as Reason R.
Assertion A : Isotopes of hydrogen have almost
same chemical properties, but difference in their
rates of reactions.
Reason R: Isotopes of hydrogen have different
enthalpy of bond dissociation.
In the light of the above statements, choose the
most appropriate answer from the options given
below:
Assertion A and the other is labelled as Reason R.
Assertion A : Isotopes of hydrogen have almost
same chemical properties, but difference in their
rates of reactions.
Reason R: Isotopes of hydrogen have different
enthalpy of bond dissociation.
In the light of the above statements, choose the
most appropriate answer from the options given
below:
View answer and explanation
Correct option: B
Both A and R are correct and R is the correct
explanation of A
explanation of A
Option B (Both A and R are correct and R is the correct explanation of A) is correct because isotopes of hydrogen have similar chemical properties due to the same electronic configuration, but different reaction rates due to different bond dissociation enthalpies.
