Options

A. `CrO_(3)`
B. `Cl_(2)`
C. `Br_(2)`
D. `CrO_(2)Cl_(2)`

Answer

D

Explanation

`(K_(2)Cr_(2)O_(7))` imparts violet colour `overset("compound"(NH_(4)Cl)+conc.H_(2)SO_(4))(to) (CrO_(2)Cl_(2))` Red gas `overset(Naoh+aGno_(3))(TO)`
`(Ag_(2)CrO_(4))` Red `ppt.overset(NH_(3)solmn.)(to)[(Ag(NH_(3))_(2)]Cl`
`(Ag_(2)CrO_(4)` Red `ppt.overset(dil.HCl)(to)(AgCl)` white `ppt.`
`(NH_(4)Cl)overset(NaOH)underset(Delta)(to) (NH_(3))` gas `(`gas white fumes with `HCl)`
