Chirality and Stereochemistry

These flashcards cover key concepts related to the assignment of stereochemistry to chiral centers, ordering of isotopes, and relevant terminology.

Chiral centers

Carbon atoms that have four different substituents attached, resulting in non-superimposable mirror images.

Ordering of isotopes

A system that ranks isotopes based on their mass; for example, br>cl>s>p>si>f>o>n>c>h³>h²>h

Stereochemical priority

The ranking of substituents attached to a chiral center based on atomic number and other criteria.

GRGS (Get Larger Isotope Sequence)

A mnemonic for remembering the order of isotopes or their increasing size.

Isotopes ranking sequence

Br > Cl > S > P > S > F > O > N > C > H; a method to prioritize substituents.

L₂

Notation that may refer to a specific stereochemistry convention or model.

Stereochemical notation

Symbols used to indicate the arrangement of groups attached to chiral centers; for instance, 'L' for inwards and '◄' for outwards.

L for inwards, ◄ for outwards

The designation of groups based on their orientation around a chiral center.
