Synthesis Flashcards
NaOH(aq) or KOH(aq) + monohaloalkane
Alcohol (Nucleophilic substitution)
NaOH(eth) or KOH(eth) + monohaloalkane
alkene (elimination)
Alcoholic alkoxide(dissolved in alcohol used to make it) + monohaloalkane
Ether (Nucleophilic substitution)
Example of alcoholic alkoxide?
Contains alkoxide ion RO- e.g CH3O-
KCN(eth) or NaCN(eth) (Ethanolic cyanide) + monohaloalkane
Nitrile (Nucleophilic substitution)
Example of ethanolic cyanide?
KCN or NaCN
What does the hydrolysis of a nitrile form?
A carboxylic acid
What mechanism do tertiary haloalkanes favour and why?
Sn1 because of steric hinderance and inductive stabilisation
What carbocation is most stable?
tertiary carbocation
Br2/Cl2 + alkene
dihaloalkane (electrophilic addition) triangular intermediate structure
Hydrogen halide ( H—X) + alkene
monohaloalkane (electrophilic addition)
Markovnikovs rule?
The X atom in H—-X bonds to the carbon with the most carbons attached to it
H2O + alkene
Alcohol (acid catalysed hydration)
Primary amine?
NH2 ( 1 H replaced)
Secondary amine?
NH (2 H replaced)
