The carboxyl group

2
Q

What is vinegar?

A

A dilute solution of ethanoic acid

3

A

Because the carboxyl group is polar like the water molecule

Like dissolves like!!

5
Q

Why do alkanoic acids have a pH below 7?

A

Because the carboxyl functional group dissociates in water to produce excess H+ (aq) ions

6
