#1
Front (Question)

What type of acids are carboxylic acids?

Back (Answer)

weak (only partially ionise in water)

#2
Front (Question)

What are MASH reactions?

Back (Answer)

Metal + acid -> salt + hydrogen

#3
Front (Question)

How do MASH reactions react?

Back (Answer)

slower

#4
Front (Question)

What are BASHO reactions?

Back (Answer)

base + acid -> salt + water

#5
Front (Question)

What are CASHOCO reactions?

Back (Answer)

Carbonate + acid -> salt + water + carbon dioxide

#6
Front (Question)

How can carboxylic acids be formed?

Back (Answer)

oxidising a primary alcohol under reflux, with acidified potassium dichromate

#7
Front (Question)

What is meant by the term derivative molecules, with regards to COOHs?

Back (Answer)

where the OH is replaced by another group

#8
Front (Question)

What are the three derivatives of COOHs?

Back (Answer)

acyl anhydride (where H2O is removed from 2 COOH groups) acyl chloride (OH replaced by Cl) amide (OH replaced by NH2)

#9
Front (Question)

how do acyl chlorides react?

Back (Answer)

nucleophilic addition-elimination reactions

#10
Front (Question)

What is the equation for the reduction of COOHs? What reducing agent is used and why?

Back (Answer)

RCOOH + 4[H] –> RCHOH + H2O LiAlH4 in dry ether NaBH4 is not reactive enough
