Stereoisomers, chirality, Examples of Handed Objects, Chirality in Molecules, Absolute Configuration, Properties of Enantiomers, Biological Discrimination,. As the main contents of the document "Stereochemistry". Invite you to consult. | Stereochemistry Isomer Organization Isomers Stereoisomers Constitutional isomers Geometric Cis/trans Conformational Isomers Enantiomers Diastereomers Meso compounds Epimers Stereoisomers Same bonding sequence. Different arrangement in space. Example: HOOC-CH=CH-COOH has two geometric (cis-trans) isomers o o => Chirality “Handedness”: right glove doesn’t fit the left hand. Mirror-image object is different from the original object Examples of Handed Objects Your hands, from the previous slide Gloves Scissors Screws Golf clubs How about molecules? Chemical substances can be handed Handed substances are said to be chiral Molecules, that are chiral are nonsuperimposable on their mirror image Chirality in Molecules cis isomers are achiral (not chiral). Chirality in Molecules The cis isomer is achiral. The trans isomer is chiral. Chirality in Molecules The cis isomer is achiral. The trans isomer is chiral. Enantiomers: nonsuperimposable mirror images, different molecules. Chirality in Molecules The cis isomer is achiral. The trans isomer is chiral. Enantiomers: nonsuperimposable mirror images, different molecules. One enantiomeric form of limonene smells like oranges, while its mirror image smells like lemons. Chirality in Molecules The cis isomer is achiral. The trans isomer is chiral. Enantiomers: nonsuperimposable mirror images, different molecules. One enantiomeric form of limonene smells like oranges, while its mirror image smells like lemons. The one enantiomer of carvone is the essence of caraway, and the other, the essence of spearmint. Most molecules in the plant and animal world are chiral and usually only one form of then enantiomer is found. Chirality in Molecules The cis isomer is achiral. The trans isomer is chiral.
