Isomers

Question 1

Structural Isomers

Answer 1

Atoms connected in a different order (functional groups, position, change)
Have different names
Two types are chain and positional
Chain isomers have different branching arrangemenets
Positional isomers have a different position of the functional group

Question 2

Stereoisomers

Answer 2

Atoms connected in the same order
Geometric isomers: Carbon single bonds rotate freely to allow these isomers (cis and trans), but there is restricted rotation around a double bond
Enantiomers: non super imposable (mirror images)

Question 3

Isomers

Answer 3

Molecules that have the same molecular formula but their atoms are arranged in different ways

Question 4

When cis-trans isomerism can occur in alkenes

Answer 4

When there are two different molecules attached to each carbon involved in the double bond

Question 5

Condensed molecular formula

Answer 5

The formula where the symbols of atoms are listed in order as they appear in the molecule’s structure. Side groups in brackets
E.g. CH3CH2CH3 for propane
