—> is an actual number of atoms

—> E.g. Ethane = C2H6

—> simplest ratio of atoms

—> E.g. Ethane = C2H6 -> CH3

—> showing all bonds

E.g. Ethanol = C2H5 OH

—> structure written according to the display formula

—> E.g. Butane : CH3CH2CH2CH3

—> skeleton structure of a compound not showing carbons or hydrogens

—> E.g. C8H18 = ////

—> solid line : represents a bond in the plane of the paper

—> solid wedge : comes out of the plane of the paper

—> dogged wedge : goes into the plane of the paper
