Assertion : Zone refining method is very useful for producing semiconductors.
Reason : Semiconductors are of high purity.

A

Both assertion and reason are true and reason is the correct explanation of assertion.

B

Both assertion and reason are true but reason is not the correct explanation of assertion.

C

Assertion is true but reason is false.

D

Assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
Correct explanation. In the zone refining method, the melt is allowed to crystallize. Since impurities are more soluble in the melt than in the pure state of the metal, therefore , ultrapure semiconductor metals are obtained after repeated crystallizations.
