Chapter 5 - Organic Nomenclature

Question 1

How many electrons do aromatic hydrocarbons have?

Answer 1

4n + 2

these are all pi electrons

Question 2

Structural isomers
Positional isomers
Functional isomers

Geometric
Optical/Enantiomers

Answer 2

All are constitutional isomers, having same chemical formula but different

Structural: different bonding
Positional: different positions of functional groups
Functional: different functional groups

All have same molecular formula but different spatial orientations
Geometric: Rotation around double bond (cis/trans), cannot conform
Optical Isomers: Non superimposible mirror images, need chrical carbon
