Which of the following statements about $IF X_{7}$ are correct?

AIt can be obtained by heating $IF X_{5}$ with $F X_{2}$ (about 523 K).
BThe molecule has a net dipole moment.
CIodine is $s p^{3} d^{3}$ hybridised.
DThere is no lone pair on the central iodine atom.

Answer: A, C, D

IF X_{7}

has seven bond pairs and no lone pairs on I, so it is

s p^{3} d^{3}

and pentagonal bipyramidal.

IF X_{5} + F X_{2} IF X_{7}

at about 523 K. The symmetric shape makes the dipole moment zero, so the last statement is wrong.
