Chapter 4- organic reactions

Question 1

Nucleophilicity

Answer 1

Increases with:

• more negative charge
• less electronegativity
• less steric hindrance
• less protic solvent

Question 2

Nucleophilicity for protic vs aprotic solvents

Answer 2

Aprotic: f->Cl-> Br> I
Protic: H helps like a carrier: I> br> Cl> F

Question 3

SN1

Answer 3

• 2 steps

- carbocation

Question 4

SN2

Answer 4

• 1 step
• stereospecific
• doesn’t occur with tertiary substrates

Question 5

Answer 5

• weak bases
• I- best
• F- worst

Question 6

Redox

Answer 6

• Pcc: primary alcohol -> aldehyde
