write reaction for oxidation of propanol with excess oxidant in two steps
Propanol is a primary alcohol ,Primary alcohols can be oxidised to either aldehydes or carboxylic acids depending on the reaction conditions. In the case of the formation of carboxylic acids, the alcohol is first oxidised to an aldehyde which is then oxidised further to the acid.
1) if you want aldehyde use an excess of the alcohol, and distil off the aldehyde as soon as it forms
2) if you need carboxylic acid use an excess of oxidant ( make sure that, the aldehydes formed in the halfway of reaction should stay in the reaction mixture, so the reaction should carried out in reflux condition )
3) Normal Oxidising used for the reaction
K2Cr2O7 Potassium dichromate OR sodium dichromate Na2Cr2O7
CrO3 Chromium trioxide
Both of these are used along with Sulfuric acid H2SO4 and water H2O
REACTIONS
( K2Cr2O7/ Na2Cr2O7)
CH3-CH2-CH2-OH + [O] -------------------------------> CH3CH2CH=O + H2O (oxygen is from oxidising agent)
( K2Cr2O7/ Na2Cr2O7)
CH3CH2CH=O + [O] -------------------------------> CH3CH2COOH + H2O
propanoic acid is final product
The full equation for the oxidation of ethanol to ethanoic acid is:

write reaction for oxidation of propanol with excess oxidant in two steps
PRELABORATORY QUESTIONS 1. When oxidations are camied out with H,Cros. usually excess oxidant is used. It is important quench this excess reagent before the reaction is worked up. What might you use to quench the exs cess oxidant? 2. Why is Cr,0,- always used in acidic, not alkaline, solution? 3. Write a balanced equation for the oxidation of cyclohexanol by hypochlorous acid, HCIO. (Note: The reduction product of hypochlorite ion is chloride ion.)

Choose a False statement regarding step 6 of glycolysis Oxidation and phosphorylation are decoupled The oxidant is NAD+ ATP not required for phosphorylation Reaction is endergonic, but the product is consumed in the next step to move the pathway forward Rationale: generation of a high-energy phosphate compound which allows for net production of ATP via glycolysis none of the answers are correct
