CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

313962 Assertion :
${ClF}_{3}$ has $T$ -shape structure.
Reason :
It has two lone pairs arranged at $180^{\circ}$ angle.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.

3 Assertion is correct but Reason is incorrect.

4 Assertion is incorrect but Reason is correct.

Explanation:

${ClF}_{3} - {sp}^{3} d$ hybridization with two lone pair of electrons. The lone pairs are at equatorial position $(120^{\circ}$ angle). Shape of the molecule is $T$ - shape.
