39:53 WE CAN DISTINGUISH BETWEEN ETHANOL AND ETHANOIC â BY ADDING SODIUM CARBONATE IN BOTH THE TEST TUBES. TESTUBE CONTAINING ETHANOIC â WILL PRODUCE CO2 GAS , AND THE TEST TUBE THAT DOESN'T FORM CO2 CONTAINS ETHANOL.
@@shalumittal1698 Yes , we can Because Ethanol does not react with NaOH Whereas Ethanoic â will react and produce salt and water. CH3COOH + NaOH → CH3COO-NA+ + H20
Aim: To Test Ethanol from Ethanoic Acid. MATERIAL REQUIRED: NaHCO3, Ethanol and Ethanoic acid. PROCEDURE: Take two test tubes A and B and add few drops of ethanol and ethanoic acid in both the test tubes then add Sodium Hydrocarbonate (NaHCO3) in both the test tubes. OBSERVATION: Then u will observe that in test tube A u will get no change but in test tube B the brisk effervescence and the carbon dioxide(CO2) get evolved. CONCLUSION: Which shows difference between Ethanol nd Ethanoic Acid by the evolution of Carbon dioxide gas.
Sir for the test can we write the activity of burning camphor and alcohol and state that where there is black smoke on the spoon those are unsaturated and other are saturated. Sir can we state this activity Kindly acknowledge
Take two test tubes add ethanol and ethanoic acid in test tube A and B respectively. Add sodium carbonate/sodium hydrogen carbonate solution in both the test tubes the test tube which will produce brisk effervescence of CO2 gas will contain ethanoic acid. Ethanol do not evolve CO2 gas when reacted with Na2CO3/ NaHCO3.
In Ethanoic acid carboxyl group is present which represents that the compound has a carboxylic functional group. In Ethanol hydroxyl group is present which represents that the compound has an alcohol functional group. Step 2: The chemical test to distinguish between Ethanoic acid and Ethanol: Sodium bicarbonate test : In the Sodium bicarbonate test, Sodium bicarbonate is added to the sample of organic acid. After some time Sodium bicarbonate reacts with the acid sample to evolve Carbon dioxide gas. Ethanoic acid reacts with Sodium bicarbonate to form Carbon dioxide with effervescence. But, Ethanol does not give any reaction with Sodium bicarbonate.
TIMING- 40:00 We can test Ethanol from ethanoic acid chemically by performing a reaction with Sodium 1. Ethanol CH 3 CH 2 OH + Na → CH 3 CH 2 ONa + H 2 (Sodium ethoxide) 2.Ethanoic Acid CH 3 COOH + Na → CH 3 COONa + H 2 (Sodium Acetate)
We can disguish between saturated and unsaturated hydrocarbon using bromine test. As in unsaturated bromine reaction show gets discolored and bro mine colour colour is constant

34:30 Sir, why can't we burn a compound to see if it's saturated or unsaturated?. What is the need of bromine water test?.
Haa yr
Bcoz saturation soln does not decolorised bromine water but unsaturated soln does.!!

Na2Co3 is aded in both test tube 39:55 and Also Esterifiction test
How esterfication?
In esterification we add both of them together and get ester right..
So how's that answered?

Ethanol do not evolve CO2 gas when reacted with Na2CO3/ NaHCO3.
Can't we put pH paper in both test tubes one is acidic and other is neutral
no because sir had told to do the chemical test...not the physical
26:00 ncert question!~
20:10 sir can we use any of the two oxidizing agents, like can we use k2c2o7 instead of kmno4 there?
yes we can do that too.
Yes but Kmno4 is widely used oxidizing agent or oxidant
Yes but that is in acidified

Sir live kab aayega😴
By using sodium carbonate

By adding soap.
Soap forms frothwith soap water while it forms scum with hard water
That hydrocarbons and carbons only react with Ethanoic acid but ethanol does not react 39:59
In Ethanoic acid
carboxyl group is present which represents that the compound has a carboxylic functional group.
In Ethanol
hydroxyl group is present which represents that the compound has an alcohol functional group.
Step 2: The chemical test to distinguish between Ethanoic acid and Ethanol:
Sodium bicarbonate test
:
In the Sodium bicarbonate test, Sodium bicarbonate is added to the sample of organic acid. After some time Sodium bicarbonate reacts with the acid sample to evolve Carbon dioxide
gas.
Ethanoic acid reacts with Sodium bicarbonate to form Carbon dioxide with effervescence.
But, Ethanol does not give any reaction with Sodium bicarbonate.
