Standard electromotive force correct answers The difference potential between two half-cells.
Ecell = Ecathode - Eanode
Gibbs free energy correct answers The energy in a system that can be used to drive chemical
reactions.
ΔG = ΔH - TΔS
Goldfish are Horrible without Tartar Sauce
, Aldol condensation correct answers A reaction in which an aldehyde or ketone acts as both the
electrophile and nucleophile, resulting in the formation of a carbon-carbon bond in a new
molecule.
Condensation reaction correct answers A reaction that combines two molecules into one, with
the loss of a small molecule.
SN1 reactions correct answers - Two steps: leaving group leaves, forming a carbocation that then
reacts with a nucleophile.
- Tertiary and secondary preferred over primary
- Racemic mixture
- Depends on the concentration of substrate
- Polar protic
SN2 reactions correct answers - Concerted single step where nucleophile attacks as the leaving
group starts to leave.
- Primary and secondary preferred over tertiary
- Changed in configuration
Depends on the concentration of both substrate and nucleophile
- Polar aprotic
Thermodynamic product correct answers favors energetically stable products even if they require
a higher activation energy and more time to produce.
Kinetic product correct answers favors products that form more quickly; these products will
often be less energetically stable but are formed faster due to lower activation energies.
