Vedclass · Answer

(A) When $NaCl$ reacts with concentrated $H_2SO_4$,it produces $HCl$ gas.$HCl$ is a diatomic molecule with $18$ electrons (even number),making it diamagnetic.$NaBr$ and $NaI$ react with concentrated $H_2SO_4$ to produce $Br_2$ and $I_2$ respectively,which are diatomic but are not the primary gaseous products expected in this context compared to the hydrogen halide gas.Thus,$NaCl$ is the correct species that yields a diatomic gas $(HCl)$ with diamagnetic behaviour.

Which of the following species gives a diatomic gas with diamagnetic behaviour upon reaction with concentrated $H_2SO_4$?
