Alkanes contain only…
MOLECULE BUILDER
Build a molecule, get its name
Organic names are a code: the start counts the carbons and the ending names the functional group. Pick a chain length and a group, and the skeletal formula, name and molecular formula update together. Each corner of the zigzag is a carbon; hydrogens are left out.
IUPAC NAMEEthanoleth- = 2 C-ol = an –OH group
C₂H₆Omolecular formula
46.1molar mass, g/mol
What this organic chemistry test covers, in short
Twenty multiple-choice questions at upper-secondary to first-year university level, four on each of five topics: hydrocarbons, functional groups, naming, isomers, and reactions and polymers.
New to chemistry? The general chemistry test covers bonding and moles first. This test is our own and not normed.
