Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): Halogens have high ionisation enthalpy.
Reason (R): Halogens have the smallest atomic radii in their respective periods.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
