Synthesis of Ethers and Naming Alkenes Flashcards
What will the reaction of an alkyl halide (R-X) with Sodium Cyanide (NaCN) produce?
A nitrile (R-CN)
What will the reaction of an alkyl halide (R-X) with Sodium attached to an unknown (NaX) produce?
A different Alkyl Halide (R-X)
What will the reaction of an alkyl halide (R-X) with Sodium Hydroxide (NaOH) produce?
An alcohol (R-OH)
What will the reaction of an alkyl halide (R-X) with water (H2O) produce?
An alcohol (R-OH)
What will the reaction of an alkyl halide (R-X) with very strong bases (e.g. R-OH or RONa) produce?
An ether (R-OR’)
Which of these reactions will occur fastest and why?
CH3I—NaBr→CH3Br
CH3I—NaF→CH3F
CH3I—NaCl→CH3Cl
CH3I—NaF→CH3F As it has the strongest nucleophile
Which side of this reaction is favoured and why? NaI+CH3Cl⇔CH3I+NaCl
NaI+CH3Cl Because I is a weaker nucleophile than Cl
What structure of molecule should an alkyl halide be reacted with to form another alkyl halide?
NaX
What structure of molecule should an alcohol be reacted with to form an alkyl halide?
HX
What structure of molecule should an ether be reacted with to form an alkyl halide?
HX
Can we use Cis/Trans notation when an alkene has four different substituents in the carbons involved in the double bond?
No
What notation do we use to name alkenes with four different substituents in the carbons involved in the double bond?
E/Z nomenclature
What is the E/Z sequence of naming alkenes used for?
Tri and tetra substiuted alkenes
When is E notation applied using the EX sequence of naming alkenes?
When there are two high priority groups on opposite sides of opposite carbons
When is Z notation applied using the EX sequence of naming alkenes?
When there are two high priority groups on the same side of opposite carbons
