One mole of a naturally occurring fat on hydrolysis with `NaOH` gave `1 mol` of glycerol together with sodium palmitate and sodium stearate in `1:2` molar ratio. The molecule of the fat is symmetric. Write down the struceture of the fat.

Text Solution

Verified by Experts

The `1:2` molar ratio of sodium palmitate and sodium stearate obtained on hydrolysis with `NaOH` indicates thate two stearate acid molecules and one palmitic acid are esterified with 1 mole of glycerol. Since the molecule of fat has symmetry, the two stearic acid molecules must be linked to two terminal primary alcoholic groups. therefore, the structure of the fat must be:
`{:(H_(2)underset(|)(C)-O-CO-C_(17)H_(35)),(Hunderset(|)(C )-O-CO-C_(15)H_(31)),(H_(2)C-O-CO-C_(17)H_(35)):}`

"Equivalent mass" =("Molecular mass/Atomic mass" )/("n-factor") n-factor is very important in redox as well as non-redox reactions.With the help of n-factor we can predict the molar ratio of the reactant species specis taking part in reactions. The reciprocal of n-factor's ratio of the reactions is the molar ratio of the reactants. In general n-factor of acid/base is number of moles of H^(+)//OH^(-) furnished per mole of acid/base n-factor of a reactant is number of moles electrons lost or gained per mole of reactant. Example 1: (1)In acidic medium : KMnO_(4) (n=5)to Mn^(2+) (2) In neutral medium : KMnO_(4)(n=3) to Mn^(2+) (3) In basic medium : KMnO_(4)(n=1) to Mn^(6+) Example 2 : FeC_(2)O_(4)to Fe^(3+)+2CO_(2) Total number of moles e^(-) lost by 1 mole of FeC_(2)O_(4) =1+1xx2 implies 3 Consider the following reaction.
