The acidic, basic or amphoteric nature of `Mn_2 O_7 ,V_2O_5, and CrO` are respectively

A

acidic, acidic and basic

B

basic, amphoteric and acidic

C

acidic, amphoteric and basic

D

acidic, basic and amphoteric

Text Solution

Verified by Experts

The correct Answer is:
D
Acidic character increases/basic character decreases with increase in oxidation state `overset(+7)(Mn_(2)) O_7` (acidic), `overset( +5)(V_2 O_5)` (amphoteric)`overset(+2)( CrO) `(basic) `(V_2 O_3 to` basic, `V_2 O_4 to` less basic, `V_2 O_5 to` amphoteric)
