Hydrolosis of esters Flashcards
1
Q
What 2 ways can esters be hydrolysed?
A
= heating with an acid
= sodium hydroxide
2
Q
How are esters hydrolysed with an acid?
A
= reagants: dilute acid hcl
= heat under reflux
= reversed reaction of formation of esters, forms a COOH acid an an alcohol
= does not give good yield of product
3
Q
How are esters hydrolysed using sodium hydroxide?
A
= reafant: dilite sodiu hydroxde
= heat under reflux
= reaction gores to completion- use excess sodium hydroxide
= forms a carboxlyic acid
= cooh acid anion can be attacked by nucleophiles and is not reversible
4
Q
What happens if we add a strong acid ?
A
= converts the salt into its acid and NaX
