Alicyclics and Aromatics

ACYLICS:

• Carbon chains can form two types of "closed" loops
• Alicylic loops usually made with single bonds
• If the parent chain is a loop standard naming rules apply with one addition: "cylo" is added in front of the parent chain. 
• 3 different ways to draw organic compounds: 

                1) Complete structural diagram

                2) Condensed structural diagram 

                3) Line diagram

• Numbering can start anywhere and go c.w. or c.c.w. on the loop but side chains numbers must be the lowest possible 
• Loops can also be a side chain
• Same rules apply but the side chain is given a cyclo -prefix

AROMATICS:

 

• Benzene (C6H6) is a cylic hydrocarbon with unique bonds between the carbon atoms
• Structurally it can be drawn with alternating double bonds 

AROMATIC NOMENCLATURE:

• A Benzene molecule is given a special diagram to show its unique bond structure
• Benzene can be a parent chain or a side chain
• As a side chain is given the name phenyl
