Precision: closeness of the set of values obtained from identical measurements of a quantity
Accuracy: closeness of a single measurement to its true value
Significant figures: digits in a measured number or calculation of measured number that
Rules for naming compounds:
1. Look for the longest carbon chain in the molecule.
a. This will be the root name of the compound.
b. There is a good table in the book with a list of all of the names for the number of
carbons that you have.
b.i. (example: 8
Matter: Physical State and Chemical Constitution
Solids, Liquids, and Gases
Solid: the form of matter characterized by rigidity; relatively incompressible, fixed shape and
volume, closely-packed particles often in regular arrays
Liquid: the form of ma
Conformers vs. constitutional isomers:
Conformers have the same connectivity but different spatial positions (due to
bond rotations). Constitutional isomers have different connectivities.

Alkanes with long straight carbon chains have higher boiling points than those with more
spherical shapes, since they are able to pack closer together and intermolecular
interactions are higher. However, compounds with compact spherical shapes pack
