NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): Semiconductors have a small band gap that allows some electrons to move to the conduction band at room temperature. | Reason (R): The lattice spacing of silicon is larger than that of carbon.
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 B
Detailed Explanation
The assertion is true because semiconductors have a small band gap allowing electron movement at room temperature. The reason is true as silicon's lattice spacing is indeed larger than carbon's, but it does not explain the assertion.
