Question | Answer |
---|---|
Protic solvent | solvent that provides a source of protons (H+) eg. water, ethanol |
Aprotic solvent | solvent that does not provide a source of protons (H+)eg. propanone, hexane |
Transition state | Unstable state that passes quickly from reactants to products |
Intermediate state | Stable state between reactants to products |
Carbocation | Carbon with a positive charge |
Markovnikov's rule | the hydrogen will attach to the carbon that is already bonded to the greater number of hydrogens |
lithium aluminium hydride (LiAlH4) | Catalyst for reduction of carboxylic acid to primary alcohol |
sodium borohydride (NaBH4). | Catalyst for reduction of ketone to secondary alcohol |
Cis isomers | Isomers with the same groups on the same side of the double bond or cyclical compounds |
Trans isomers | Isomers that have the groups on the opposite sides of the double bond |
E isomers | somers with >2 different groups and have the two most important group opposite |
Z isomers | Isomers with >2 different groups and have the two most important groups on the same side |
Chiral carbon | Carbon that have 4 different groups |
Enantiomers | Optical isomers that exist in pairs |
Diastereomers | Optical isomers that contain two or more chiral carbons that are not mirror images of each other |
