    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

    Q- why is alcohol soluble in water, and why are ketones not reduced by the tollen's test.😃😇
