Frequently asked questions
What is Organic chemistry?
Organic chemistry covers Introduction to organic chemistry, Alkanes, Halogenoalkanes, and Alkenes in AS Level AQA Chemistry. 35 lessons in 7 subtopics.
What is LPG?
LPG, liquefied petroleum gas, is mainly propane, C₃H₈, and butane, C₄H₁₀, used as fuel in portable stoves and for heating. The Fuels and Combustion notes cover this in full.
What is the general formula of alkenes?
The general formula of straight-chain alkenes is CₙH₂ₙ. The Alkenes: Structure and Bonding notes cover this in full.
What is cracking in chemistry?
Cracking is the breaking of C–C bonds in long-chain alkane molecules to form shorter-chain molecules. The Cracking Alkanes: An Introduction notes cover this in full.
What is a free radical?
A free radical is a species with one unpaired electron, shown by a dot next to its symbol, such as Cl· or CH₃·. The Understanding Reaction Mechanisms notes cover this in full.
What is the general formula for alcohols?
The general formula for alcohols is CₙH₂ₙ₊₁OH, where n is the number of carbon atoms. The Formulae in Organic Chemistry notes cover this in full.
What is a homologous series?
A homologous series is a family of compounds with the same functional group and the same general formula, with each successive member differing by one CH₂ unit. The IUPAC Nomenclature and Homologous Series notes cover this in full.
What is an alkane?
An alkane is a saturated hydrocarbon: it contains only carbon and hydrogen, and every carbon-carbon bond is a single bond, with no C=C or C≡C bonds. The Introduction to Alkanes and Fractional Distillation notes cover this in full.
What are polar stratospheric clouds?
Polar stratospheric clouds form at the very low temperatures over polar regions. The Mechanism of Ozone Depletion notes cover this in full.
