Assertion: Cr(VI) in the form of dichromate in acidic medium is a strong oxidising agent where MoO3 and WO3 are not. Reason: In d-block elements higher oxidation states are favoured by heavier members.

Q. Assertion : $C r (V I)$ in the form of dichromate in acidic medium is a strong oxidising agent where $M o O_{3}$ and $W O_{3}$ are not.
Reason : In $d$ -block elements higher oxidation states are favoured by heavier members.
