Isomers

Question 1

Isomer

Answer 1

molecules that share the same chemical formula but differ in their structure

Question 2

Structural Isomers (constitutional)

Answer 2

different ways atoms can be connected

Question 3

Functional Isomers

Answer 3

structural isomers with different functional groups

Question 4

Tautomers

Answer 4

structural isomers that interconvert with each other and exist in equilibrium

Question 5

Stereoisomers

Answer 5

same functional groups, different spatial configuration

non-superimposable mirror images

Question 6

Conformational Isomers

Answer 6

anti vs eclipsed (think gauche)

Question 7

Anti Conformation

Answer 7

180 degree separation

Question 8

Gauche Conformation

Answer 8

60 degree separation

Question 9

Angle Strain

Answer 9

occurs when the angle between single bonded c-atoms deviates from 109.5

Question 10

Torsional Strain

Answer 10

created by eclipsing substituents on neighboring atoms

Question 11

Steric Strain

Answer 11

caused by substituents getting in each others way

Question 12

Cis/Trans Isomers

Answer 12

geometric isomer

refers to the positioning of 2 identical substituents across a double bond
