Question

Which of the following statements is/are correct regarding ${IF}_5$ molecule?

(I) There is only one lone pair present in equatorial

(II) All $\angle FIF$ angles are identical

(III) There are eight faces in this molecule

(IV) The number $\angle FIF$ angles less than ${90}^0$ is 8

• A. I,II and III
• B. II,III and IV
• C. III and IV
• D. III only

Answer 1

Answer: (B)

II,III and IV

It has a square pyramidal geometry. In the equatorial plane it has one lone pair.

All the $F-I-F$ angles are equal of ${81.9}^o$

The number of $F-I-F$ angle is not 8 but it is less than ${90}^o$
