Consider: (i) $IF X_{7}$ is pentagonal bipyramidal with $s p^{3} d^{3}$ iodine; (ii) $XeF X_{6}$ and $IF X_{6} X^{-}$ have the same number of valence electrons; (iii) $BrF X_{5}$ and $XeF X_{4}$ are isostructural; (iv) $ICl X_{2} X^{-}$ and $XeF X_{2}$ have the same number of lone pairs on the central atom; (v) $XeF X_{2}$ and $BrF X_{2} X^{+}$ are both linear. The number of correct statements is

(i) is true: 7 bond pairs, no lone pair. (ii) is true:

XeF X_{6}

has

8 + 42 = 50

and

IF X_{6} X^{-}

has

7 + 42 + 1 = 50

. (iii) is false:

BrF X_{5}

is square pyramidal with 1 lone pair and

XeF X_{4}

is square planar with 2. (iv) is true: both have 3 lone pairs on the central atom. (v) is false because

BrF X_{2} X^{+}

is bent. Three statements, (i), (ii) and (iv), are correct.
