Basic Concepts and Hydrocarbons Flashcards
Define a General Formula
An algebraic formula that can describe any member of a family of compounds
Define a empirical formula
The simplest whole number ratio of atoms of each element in a compound (cancel the numbers down if possible)
What is the empirical formula of ethane, C2H6?
CH3
Define molecular formula
The actual number of atoms of each element in a molecule
Define Structural formula
Shows the arrangement of atoms carbon by carbon, with the attached hydrogens and functional groups
Define skeletal formula
Shows the bonds of the carbon skeleton only, with any functional groups. The hydrogen and carbon atoms aren’t shown. This is handy for drawing large complicated structures, like cyclic hydrocarbons.
Define Displayed formula
Shows how all the atoms are arranged, and all the bonds between them.
What are the general groups called in organic chemistry?
Homologous series
What is a homologous series?
A group of organic compounds that have the same functional group and general formula

What is a hydrocarbon?
A compound containing only carbon and hydrogen atoms
What does saturated mean?
Organic compounds containing only single (sigma) bonds
What does unsaturated mean?
Organic compounds containing one or more double or triple bonds
What is a homologous series?
A series of organic compounds having the same functional group but with each successive member differing by a CH2 group.
