FINAL: Acid/Base Chemistry

Question 1

What is the definition of an acid

Answer 1

A compound containing an atom or just an atom, which is electron deficient (aka an electrophile)
Electron acceptor

Question 2

What is the definition of a base

Answer 2

A compound containing an atom which is electron rich, aka a nucleophile
(Electron donor)

Question 3

How do you determine the arrows of equilibrium?

Answer 3

Point them towards the weaker acid aka higher pka value

Question 4

How to determine CA or CB

Answer 4

The conjugate is the opposite of the original structure

Question 5

When are the arrows of equilibrium equal

Answer 5

when the pkas are within 2 units

Question 6

What is the form of the structure when pH>pKa

Answer 6

deprotenated, or missing a hydrogen
Basic Form

Question 7

What is the form of the structure when pH<pKa

Answer 7

Protenated, additional hydrogen
Acidic Form

Question 8

what does acidic vs basic form mean

Answer 8

acidic: additional hydrogen or positively charged
basic: less hydrogen or negatively charged

Question 9

What is the acidic form and basic form of carboxylic acids

Answer 9

it is neutral in its acidic form and charged in its basic form
