Chem 4 Flashcards
Mechanism between a aldehyde and a ketone and cyanide
Nucleophilic addition
Homogeneous system
Where all the reactants and products are in the same state
Reducing agent from ketone to a alcohol
NaBH4
Conditions for esterification
Reagents: conc sulphuric acid plus carboxylic acid and alcohol
Conditions: heat/warm
Reduction of esters into alcohols
Sodium hydroxide
Forms original alcohol and the -oate forms with the sodium
Advantage of using propanoyl chloride instead of prop anoxic acid in the lab for prep of methyl propanoate from methanol
Gives a bigger yield
Equation between acid and bases before equivalence point
CO3 + H -> HCO3
Equation between acid and base at equivalence
HCO3 + H -> H2O + CO2
Fingerprint region for IR spectrum
400-1500cm
Give reagents and conditions for formation of nitrobenzene from benzene. Plus mechainism
Conc nitric acid and conc sulphuric acid
Electrophilic substitution
Reagents for conversion from nitrobenzene to amino benzene
Sn and sulphuric acid
What happens to an amino acid in sodium hydroxide
Oxygen becomes charged
What happens to an amino acid in Hydrochloric acid
The nitrogen becomes charged
Reaction with methanol in the presence of small amount of concentrated sulphuric acid and amino acid
The alcohol adds an R group onto it
Amino acid reaction with ethanoyl chloride
The ethanoyl part attaches to the nitrogen
