NEET Chemistry Transition Elements Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): Transition elements have higher enthalpies of atomisation compared to s-block elements. | Reason (R): Transition elements have a greater number of unpaired electrons leading to stronger interatomic interaction.
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.
Correct Answer
Option A
Detailed Explanation
The assertion is true because transition elements possess higher enthalpies of atomisation due to the stronger bonding attributed to the larger number of unpaired electrons, which is accurately explained by the reason.
