JEE Main 2024 — 29 January, Shift 2 — Question 63

The correct IUPAC name of $\mathrm{K}_{2} \mathrm{MnO}_{4}$ is

Option A:
Potassium tetraoxopermanganate (VI)
Option B:
Potassium tetraoxidomanganate (VI)
Correct
Option C:
Dipotassium tetraoxidomanganate (VII)
Option D:
Potassium tetraoxidomanganese (VI)

Answer: B
