For the following reaction, select the statement that best describes the change.
`RCH_(2)OH+PC C [C_(5)H_(5)NH^(+)ClCrO_(3)^(-)] rarr`

Options

A. The alcohol is oxidized to an acid, and the `Cr (VI)` is reduced
B. The alcohol is oxidized to an aldehyde, and the `Cr (VI)` is reduced
C. The alcohol is reduced to an aldehyde, and the `Cr (III)` is oxidized
D. The alcohol is oxidized to a ketone, and the `Cr (VI)` is reduced

Answer

B

Explanation

`Cr^(+6) rarr Cr^(+3)` (PCC oxidises `1^(@)` alcohol to aldehyde)
