BRAINCAKEChirality
Revision notes for Chirality in Edexcel Chemistry (9CH0). Every lesson in BrainCake comes with R.E.C.I.P.E. recall steps, a quick check and spaced reviews.
- ChiralitySome molecules exist in two forms that are mirror images of each other but cannot be placed exactly on top of each other, just as your left and…
- Optical IsomersA chiral molecule exists as two optical isomers, also called enantiomers.
- Plane-Polarised LightOrdinary light is made of electromagnetic waves that vibrate in all planes at right angles to the direction the light travels.
- Racemic MixturesA racemic mixture (or racemate) is a mixture containing equal amounts of the two enantiomers of a chiral compound.
- Racemates from Nucleophilic AdditionAldehydes and ketones react with hydrogen cyanide by nucleophilic addition to form hydroxynitriles.
- Identifying Chiral CentresTo decide whether a molecule is chiral, look for a chiral centre: a carbon atom with four different groups attached.
