1

What is a Displacement reactions?

When one molecule is displaced and replaced by another

2

What is a nucleophile?

An electron rich molecule that can be charged or neutral that donates its electrons to the nucleophile

3

What is an electrophile?

The molecule that is usually neutral and has the alpha carbon which accepts an electron pair

4

What is the extra step that neutral nucleophiles have to undergo?

The lose one of their hydrogens to water to make hydronium ion and another neutral molecules

5

How does the SN2 reaction affect chirality?

It inverts the chiral center. So if it was S its then R

6

How does a negatively charged nucleophile affect nucleophilicity?

Negative atoms have more electrons to share so it increases nucleophilicity

7

How does Higher electronegativity affect nucleophilicity?

Atoms with higher electronegativity are less likely to share electrons which reduces electrophilicity

8

How does Atomic Size affect nuclophilicity?

Large atomic size creates a more polarizable electron cloud which increases nucleophilicity

9

How do resonance structures affect nucleophilicity?

Nucleophiles with resonance structures are more stable and less likely to share electrons
