a)
Interpretation:
The products need to be predicted when tripalmitolein is treated with the given set of reagents.
Concept introduction:
Reduction is a reaction in which hydrogen is added to the given compound. One of the examples is conversion of unsaturated bonds to saturated bonds.
To predict: the product formed when tripalmitolein is treated with excess hydrogen and nickel.
a)
Answer to Problem 29PP
Solution:
The product predicted when tripalmitolein is treated with hydrogen and nickel is,
Explanation of Solution
Structure of tripalmitolein
The structure of tripalmitolein is drawn as above. In tripalmitolein there are three double bonds.
Reaction with excess hydrogen and nickel.
When tripalmitolein is treated with excess hydrogen and nickel, all the double bonds present in the fatty acid residue are reduced to saturated bonds to give a saturated triglyceride as shown above.
The product formed when tripalmitolein undergoes reaction with excess hydrogen and nickel is a saturated triglyceride and the structure is,
(b)
Interpretation:
The products need to be predicted when tripalmitolein is treated with the given set of reagents.
Concept introduction:
When triglyceride is treated with aqueous sodium hydroxide, the ester group is hydrolyzed to give glycerol and the fatty acid as carboxylate ion.
To predict: the product formed when tripalmitolein is treated with aqueous sodium hydroxide.
(b)
Answer to Problem 29PP
Answer
The product obtained when tripalmitolein is treated with aqueous base is,
Explanation of Solution
Structure of tripalmitolein
The structure of tripalmitolein is drawn as above. In tripalmitolein there are three ester groups.
Reaction with excess hydrogen and nickel.
When tripalmitolein is treated with aqueous sodium hydroxide the ester group is hydrolyzed to form glycerol and fatty acid carboxylate ion.
The product formed when tripalmitolein is treated with aqueous sodium hydroxide is glycerol and three equivalents of carboxylate ion,

- 1. For each of the following statements, indicate whether they are true of false. ⚫ the terms primary, secondary and tertiary have different meanings when applied to amines than they do when applied to alcohols. • a tertiary amine is one that is bonded to a tertiary carbon atom (one with three C atoms bonded to it). • simple five-membered heteroaromatic compounds (e.g. pyrrole) are typically more electron rich than benzene. ⚫ simple six-membered heteroaromatic compounds (e.g. pyridine) are typically more electron rich than benzene. • pyrrole is very weakly basic because protonation anywhere on the ring disrupts the aromaticity. • thiophene is more reactive than benzene toward electrophilic aromatic substitution. • pyridine is more reactive than nitrobenzene toward electrophilic aromatic substitution. • the lone pair on the nitrogen atom of pyridine is part of the pi system.arrow_forwardThe following reactions are NOT ordered in the way in which they occur.
