Text Solution

Verified by Experts

The correct Answer is:
B
A primary alcohol may be oxidized to an aldehyde or to a carboxylic acid.
`RCH_(2)OH overset([o])(rarr)RCHOoverset([O])rarr RCOOH`
Strong oxidising agents such as acidified `KMNO_(4)`, are used for getting carboxylic acids directly, while `Cr(+6)` in anhydrous medium is used as the ocidising agent for the isolation of aldehydes. Secondary alcohols are oxidized to ketones by chromic anhydride `(CrO_(3))`:

Tertiary alcohols having no `H` on carbon bearing`-OH` group do not under oxidation reaction under neutral or alkaline conditions. however, they can be oxidized to ketones and or carboxylic acids via alkenes.
