Card preview (24)
Toulene with acetic anhydride and chromium oxide give
benzaldehyde
Gatterman Koch reaction reagent and product
aldehydes or ketones, Hydrocarbon,alcohol boiling point
Does aldehydes have odour !? if yes! Which kind lower/higher
yes aldehydes have odour a pungent which is inversely proportional to the number of carbons, the lower aldehydes
Structure of vanilla
Addition of HCN to ketone followed by H3O+
adding HCN to ketone would fform a cyanohydrin which then followed by H3O+ will form a carboxylic acid on the C which was attached to N
Strecker synthesis gives
Amino Acids
Aldehyde/ketones with alcohol forms ___ and what does it changes to and why
hemiacetal and it changed to acetal as hemiacetal is unstable
How are aldehydes protected and how are they released again?
the cyclic ketal formed with addition of ethan-di-ol protects the ketone and it can be changed again to ketone by adding water
Addition of water to ketones/aldehydes
gem diol is formed
Ninhydrin test is for what compounds, whats the structure of ninhydrin and whats the color of the product
the test is for primary amine or NH3 the color is purple blue
If hydroxylamine is added to ketone/aldehyde
oxime is formed by dehydration
If hydrazine is added to ketone/aldehyde
hydrazone is formed by dehrdration
If phenylhydrazine is added to ketone/aldehyde
phenylhydrazone
Beckman rearrangement in oximes
Aldol reaction shortcut
Intramolecular aldol condensation
Cannizaro reaction what happens
Whats the major product for formaldehyde and why?
Oxidation product HCOOH cause ther eis no grp to reduce the delta +ve charge on the carbonyl carbon
Intramolecular cannizaro
Perkin reaction
Tiochenko reaction
Carbonyl compound reaction with PCl5
acid chloride with Pd BaSO4 + H2 forms
Aldehyde
