Flashcards in Carboxylic Acids & Derivatives Deck (11):
1

alcohol+carboxylic acid->

ester+water, reflux, strong acid catalyst eg conc.H2SO4, REVERSIBLE

2

alcohol +acyl chloride ->

ester+HCl, reflux, dry conditions

3

alcohol +acid anhydride->

ester+carboxylic acid, reflux, dry conditions

4

alcohol +acid anhydride->

ester+carboxylic acid, reflux, dry conditions

5

ester+water-> (acidic)

carboxylic acid+alcohol, acid=catalyst

6

ester+water-> (alkaline)

ester +NaOH(aq)-> carboxylate salt + alcohol sapenification

7

carboxylic acid ->acyl chloride

SOCl2 (thionyl chloride), dry conditions, chlorination, carboxylic acid+SOCl2->acyl chloride+SO2+HCl

8

acyl chloride+water->

carboxylic acid +HCl (dense white fumes)

9

acyl chloride+ammonia->

primary amide+HCl (with excess ammonia, HCl forms ammonium salt)

10

acyl chloride +amine->

secondary amide+HCl (with excess amide HCl reacts to form a salt)

11

making acid anhydrides

2×carboxylic acid <> acid anhydrides +H2O
