Both these are hydrocarbons (as is methane), i.e. they contain only carbon and
hydrogen.
Note that carbon is tetravalent in all cases, i.e. it forms four bonds to other
atoms. In the above two examples some valencies are satisfied by bonding to
other carb
Light striking the pigment triggers rotation around a carbon-carbon double
bond, transforming rhodopsin into metarhodopsin II. The change in molecular
shape causes a nerve impulse to be sent to the brain, which is translated into a
visual image. Eventuall
Hydrogen can add across a double bond under certain circumstances and the
reaction is exothermic ( H = 120 kJ mol1 ), i.e. heat is evolved. But
hydrogenation reactions typically have high energies of activation, so that an
alkene and hydrogen will not rea
Topic 3C - Alkanes
Key questions
Alkanes; hydrocarbons; saturated hydrocarbons. What are these? Why are they
so prevalent, and what are their structural features and their chemical
properties? In this section we will explore the simplest class of organic

Topic 3B - Bonding in carbon compounds
Key questions
How can carbon bond in three different geometries? How do three orthogonal
p-orbitals and an s orbital allow this to happen? The answer lies in VB theory
or, better still, MO theory. How does this theor

How do we name this multitude of alkanes, and indeed all organic compounds?
If they were given individual, unrelated names we could never derive the
structure from the name; nor could we remember which structure fitted
