Assertion : CrO(3) is an acid anhydride....

Assertion : `CrO_(3)` is an acid anhydride.
Reason: `CrO_(3)` is obtained as bright orange crystals by the reaction of `K_(2) Cr_(2) O_(7)` with cold concentrated `H_(2) SO_(4)`.

A

Statement-1 is true , Statement-2 is true and Statement-2 is correct explanation for Statement-1

B

Statement-1 is true, Statement-2 is True and Statement-2 is Not correct explanation for statement-1

C

Statement-1 is true, Statement-2 is False

D

Statement-1 is False, Statement-2 is True

Text Solution

Verified by Experts

The correct Answer is:
B
Statement-1: correct statement as it gives oxy `H_(2)Cr_(2)O_(7),2CrO_(3)+H_(2)OtoH_(2)Cr_(2)O_(7)`.
Statement-2: Correct statement ,
`K_(2)Cr_(2)O_(7)+2H_(2)SO_(4)("concentrated and cold") to CrO_(3)downarrow("bright orange")+2KHSO_(4)+H_(2)O.`
