Oxidation to carboxylic acids [H2CrO4\u00a0+ others]<\/h1>

Oxidation to carboxylic acids [H2<\/sub>CrO4<\/sub>\u00a0+ others] Definition:<\/h2>

Primary alcohols<\/strong>\u00a0treated with\u00a0chromic acid<\/strong>\u00a0will be converted to\u00a0carboxylic acid<\/strong>.<\/p>

\"\"<\/p>

Oxidation to carboxylic acids [H2<\/sub>CrO4<\/sub>\u00a0+ others] Explained:<\/h2>

Oxidation<\/strong>\u00a0is a reverse process which involves an increase in oxidation state.<\/p>

The outcome of an oxidation process depends on the starting alcohol. If we have\u00a0primary alcohol<\/strong>\u00a0which has two hydrogen atoms at the\u00a0\u03b1 position, it can be oxidized twice. The first oxidation yields an\u00a0aldehyde<\/strong><\/a>, and further oxidation of this aldehyde gives the\u00a0carboxylic acid<\/strong>.\u00a0Secondary alcohols<\/strong>\u00a0only have one proton at the\u00a0\u03b1 position so they can only be oxidized once, forming a\u00a0ketone<\/strong>\u00a0<\/a>that cannot be oxidized further.\u00a0Tertiary alcohols<\/strong>\u00a0do not undergo oxidation because they do not have any protons at the\u00a0\u03b1 position.<\/p>

Chromic acid<\/strong>\u00a0(H2<\/sub>CrO4<\/sub>) is mainly used to produce a carboxylic acid. It can be formed either from chromium trioxide (CrO3<\/sub>) or from sodium dichromate (Na2<\/sub>Cr2<\/sub>O7<\/sub>) in aqueous acidic solution.<\/p>

This mechanism consists of two main steps:<\/p>

STEP 1:<\/strong>\u00a0Formation of a chromate ester from a primary alcohol and chromic acid.<\/p>

\"\"
STEP 2<\/b>: E2 process form a carbon-oxygen \u03c0 bond<\/p>

\"\"
Here obtained an aldehyde which is difficult to isolate. This reaction goes further to carboxylic acid<\/b> by protonation.<\/p>
