NEET Chemistry (general) Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 11
Assertion (A): The first member of the p-block elements shows a greater ability to form pπ-pπ multiple bonds compared to subsequent members of the same group. | Reason (R): The first member of each p-block group has nine valence orbitals, allowing for expanded covalency.
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 C
Detailed Explanation
The assertion is true as the first member of p-block elements can form strong pπ-pπ bonds due to effective overlap. However, the reason is incorrect because the ability to form multiple bonds is not due to the availability of nine valence orbitals.
