Organic Chem
The molecular formula C4H10 only shows you the number of each
atom, but not how they’re actually connected.
The Condensed Structural Formula CH3CH2CH2CH3 this shows the
grouping of atoms
The 2D structural formula (lewis structure) shows all atoms as well as
bonds which is good for connectivity, but bad for 3D shape.
The 3D drawing/Wedge-dash best shows the 3D, tetrahedral geometry
around carbon atoms.
Dashed line, pointing away from you.
Solid triangle line, pointing towards you.
Normal line, on plane of page
Whatever's in brackets Connected to carbon before it.
Saturated hydrocarbon ONLY single bond (sigma bond)
Unsaturated hydrocarbon DOUBLE (1 sigma, 1 pi bond) and/or TRIPLE
(1 sigma, 2 pi bond) bonds.
