6. SN1 and SN2 Reactions

Question 1

What is a Displacement reactions?

Answer 1

When one molecule is displaced and replaced by another

Question 2

What is a nucleophile?

Answer 2

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

Question 3

What is an electrophile?

Answer 3

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

Question 4

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

Answer 4

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

Question 5

How does the SN2 reaction affect chirality?

Answer 5

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

Question 6

How does a negatively charged nucleophile affect nucleophilicity?

Answer 6

Negative atoms have more electrons to share so it increases nucleophilicity

Question 7

How does Higher electronegativity affect nucleophilicity?

Answer 7

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

Question 8

How does Atomic Size affect nuclophilicity?

Answer 8

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

Question 9

How do resonance structures affect nucleophilicity?

Answer 9

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