NEET Chemistry (general) Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 11
Assertion (A): The formation of CaF2 involves the transfer of electrons from calcium to fluorine. | Reason (R): Ionic bonds result from the electrostatic attraction between ions with opposite charges.
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.
Correct Answer
Option A
Detailed Explanation
The NCERT context mentions that the formation of CaF2 involves calcium losing electrons to form Ca2+ and fluorine gaining electrons to form F-. The ionic bond is due to the electrostatic attraction between Ca2+ and F-, which explains why A is true and R is the correct explanation of A.
