Chromic anhydride in `H_(2)SO_(4)` is not blue by:A. a.`1^(@)` alcoholB. b.`2^(@)` alcoholC. c.`3^(@)` alcoholD. d.

Answer» Correct Answer - C
Since `3^(@)` alcohols are not oxidised by `("chromic anhydride" + H_(2)SO_(4))` or `(Cr_(2)O_(7)^(2-)+ H_(2)SO_(4))`, so no change of `Cr^(6+)` to `Cr^(3+)`. Hence, no change of colour.
