1
Q
How are esters formed?
A
= COOH acids react with alcohols in the pressence of a strong acid catalyst to form esters and water
2
Q
Where are the 2 parts of the name come from?
A
= -anoate comes from the caroxylic acid including the C
= and -yl comes from the alcohol
= that is formed from the single bonded alcohol
3
Q
Where does the water come from?
A
= a hydrogen from the OH and hydrogen from the alcohol
4
Q
What kind of acid catalyst is used?
A
= concentrated sulfuric acid
5
Q
Is the reaction reversible?
A
= yes
= slow and heated in relfux
