Chromic Acid test Flashcards
The chromic acid test uses what reagent?
Chromic Acid
What does the chromic acid test for ?
Primary and secondary alcohols
What color is the reagent chronic acid
Bright orange
Upon reaction with alcohols,the reagent changed from what color to what color?
Orange to gree
Is chronic acid a strong oxidant
Yes
When primary and secondary alcohols are exposed to chronic acid, what happens
They are oxidized
Meaning the number of carbon oxygen bonds increase and the number of carbon abd hydrogen bonds decrease
When primary alcohols are oxidized by chronic acid, what is formed?
Carboxylic acid
When secondary alcohols are oxidized, what is formed
Ketone
Does the reaction occur woth tertiary alcohol? Why?
No, the carbon atom, in a tertiary alcohol has the maximum number of c-c bonds possible so it can’t create more c-o bonds
What chemical species is responsible for color change?
Sulfuric acid, chromic 3 oxide
Cr6+ changes to an oxidation state of
Cr3+
