Use F = $- 1$ , O = $- 2$ . In bleaching powder $CaOCl X_{2}$ take the structure $Ca (OCl) Cl$ (one hypochlorite and one chloride). Select ALL correct statements.

ACl in $Cl X_{2} O X_{7}$ is $+ 7$
B $CaOCl X_{2}$ contains Cl in both $+ 1$ and $- 1$ states
CI in ICl is $+ 1$ (Cl more electronegative)
DBr in $BrF X_{5}$ is $+ 3$

Answer: A, B, C

Cl X_{2} O X_{7}

:

2 x = 14

, Cl = +7. In

Ca (OCl) Cl

,

OCl X^{-}

has Cl = +1 and

Cl X^{-}

is

- 1

. In ICl, I = +1. In

BrF X_{5}

, Br = +5, not +3.
