Front (Question)

Quarternary Carbon

Back (Answer)

Bonded to four Cs

Front (Question)

Back (Answer)

Differ in the way the atoms are connect to each other

Front (Question)

IUPAC Rules

Back (Answer)

• FInd the longest chain of carbons and use it as the base • Name the attached groups using the location of each alkyl group by the number of the Carbon it’s attached to • Write alkyl groups in alphabetical order regardless of their position on the chain

Front (Question)

Naming Alkyl Groups (1 Carbon to 5 Carbons)

Back (Answer)

Methane, ethane, propane, butane, pentane

#10

Front (Question)

Iso grouping

Back (Answer)

When the Cs form a triange CH3 CH – CH3

#11

Front (Question)

Newman Projections – Eclipsed

Back (Answer)

The two molecules are almost on top of each other. Causes steric crowding and is high in energy

#12

Front (Question)

Newman Projections – Staggered

Back (Answer)

The Hs are is spread out equally. Less steric crowding, lower in energy

#13

Front (Question)

Keq equation (energy)

Back (Answer)

Keq = 10 ^ (± (3/2)∆E)

#14

Front (Question)

Back (Answer)

Gauche (60° between methyls) Anti (180º between methyls)

#15

Front (Question)

HIgher alkanes resemble ______ in their preference for _____ and _____ conformations about the carbon-carbon bonds

Back (Answer)

Butane, anti and gauche

#16

Front (Question)

Geometric Isomers

Back (Answer)

Same molecules connected to the same carbons, but one is cis and one is trans

#17

Front (Question)

Cis molecule

Back (Answer)

The methyl groups are on the same side of the molecule

#18

Front (Question)

Trans molecule

Back (Answer)

The methyl groups are on opposite sides of the molecule

#19
