For Alcohol
- Add ethanol in test tube (Alcoholic Smell)
-Add some drops of Water (No Physical change as alcohols are water soluble)
-Acidic Nature : Slightly Acidic (pH : 6 to 7)
-C.A.N Test
Add some drops of cerric ammonium nitrate in pure alcohol and you will see the colour change from colourless to Red
For Ketones
-Add some Acetone in test tube
-It would have Nail Polish Remover like smell
-Add some drops of water , If no change occurs that means ketone is soluble in water , Therefore we can conclude it must be a lower Ketone (Less Carbon)
- Nature : Slightly Acidic (pH: 6 to 7)
Test 1 :
- Add some NaOH in dil Acetone
- Add some drops of Sodium nitropruisside and you will a color change from colourless to Reddish Black
Test 2
-Add NaOH in dil Acetone
-Add crystals of m-Di Nitro Benzene
And it will change its colour from colourless to Purple Which confirms that it is ketone

alcohols:
-ceric amm nitrate(yellow, few drops)+ alcohols = red\orange sol
ketones:
ketone in basic medium first(naoh)
- m-dinitrobenzene crystals(flaky, yellow) + basic ket. sol = violet
- sodium nitroprusside sol + basic ket. sol = blood red
thank you so much mam.. your videos are awesome .❤️❤️❤️
Ma'am how to make cerric ammonium nitrate solution?
Ma'am please tell.
In physical apperance
Hume school mein likhaya gya ki
State solid hoti hai
Colour white hota hai
Odour odourless hota hai
Aur solubility insoluble in water hota hai🙄
ye kisi salt ka hoga
it is liquid sample
