Question
hoose the correct statements from the followingA. Mn2O7 is an oil at room temperatureB. V2O4 reacts with acid to give VO2+2C. CrO is a basic oxideD. V2O5 does not react with acidChoose the correct answer from the options given below :A, B and D onlyA and C onlyA, B and C onlyB and C only
Solution
The correct answer is "A, B and C only".
Here's why:
A. Mn2O7 is an oil at room temperature - This is correct. Manganese heptoxide (Mn2O7) is a dark green oily liquid at room temperature.
B. V2O4 reacts with acid to give VO2+2 - This is correct. Vanadium(IV) oxide (V2O4) reacts with acid to form the VO2+ ion.
C. CrO is a basic oxide - This is correct. Chromium(II) oxide (CrO) is a basic oxide, meaning it reacts with acids to form a salt and water.
D. V2O5 does not react with acid - This is incorrect. Vanadium(V) oxide (V2O5) does react with acid to form a salt and water.
