Chemistry (AS Level)·Carboxylic acids and derivatives · NSSCAS 4.7.2
Esters & Amines
Narrated lesson · press play
Meet two more organic families. You'll recognise the –COO– ester linkage and the –NH₂ amine group in condensed, displayed and skeletal formulae, name esters from their parent alcohol and acid (like methyl ethanoate) and name primary amines (like 2-aminobutane). You'll deduce molecular formulae from a structure, work through both acid and base hydrolysis of esters and DRAW the products, and explain why esters make such good solvents, perfumes and flavourings.
What you'll learn in this lesson
By the end you should be able to (NSSCAS Chemistry (AS Level) 4.7.2):
- Interpret and use general, structural (condensed and displayed) and skeletal formulae of primary amines (the –NH₂ group) and esters (the –COO– ester linkage)
- Name esters from the parent alcohol and carboxylic acid, and name primary amines, up to six carbons (e.g. methyl ethanoate, 2-aminobutane)
- Deduce the molecular formulae of esters and primary amines from a given structure
- Describe the acid and base (alkaline) hydrolysis of esters and draw the structures of the products
- Explain why esters are used as solvents, perfumes and flavourings
