OChem Exam 3-Ashton Sanchez 11/24/25

In a ring flip for a chair conformation

axial and equatorial are switched, keeping specific bonds

1-3 Diaxial strain

Occurs on axial carbons, when bulky groups have interfering interactions with each other (bulky groups will have less strain when equatorial)

achiral

achiral is one that is superimposable on its mirror image

chiral

chiral is one that is NOT superimposable on its mirror image

optically active

pure chemical either S or R conformation

optically inactive

achiral compound or a racemic mixture

Anti addition to a E alkene

substituents will add with opposite bond types (one dashed, one wedged)

Anti addition to a Z alkene

substituents will add to the same bond type e.g. both dashed/wedged

Syn addition to a E alkene

substituents will add to the same bond type e.g. both dashed/wedged

Syn addition to a Z alkene

substituents will add with opposite bond types (one dashed, one wedged)

Strong bases are good nucleophiles

true

SN2 Reaction

bimolecular nucleophilic substitution (always a backside attack of NU compared to LG)

SN1 Reaction

unimolecular nucleophilic substitution

SN2 rxns reverse stereochemistry

true

E2 Reaction

Bimolecular elimination

E1 Reaction

unimolecular elimination
