New cards

What are amines?

Basic

2
New cards

Why are amines basic?

Presence of lone pair of electrons in N which accepts protons

3
New cards

What happens when amines react with acids?

Leads to amine salts

4
New cards

What is the strength of a base determined by?

Readiness to accept protons

5
New cards

What does the readiness to accept protons depend on?

Size of delta negative charge on N atom, availability of N lone pair

6
New cards

What compounds increase basic strength?

Electron donating groups like alkyl groups

7
New cards

Why do electron donating groups like alkyl groups increase basic strength?

Increases electron density of N lone pair. Cation is more stable

8
New cards

What compounds decrease basic strength?

Electron withdrawing groups like C6H5

9
New cards

Why do electron withdrawing groups like C6H5 decrease basic strength?

decreases electron density of N lone pair. Cation is less stable
