So what are Alkenes? Draw a simple
first alkene, name it.

Hydrocabons
Aliphatic
Alkenes are
hydrocarbons in which
one of the C-C bond
contains a carbon-carbon
double bond.

(H2- C=C- H2)

Eg. Ethene is the first


member of the
family(Alkene)

Class Activity(Recap)
1. What is the correct line-bond structural formula for the compound shown
below? (The black dots are bonding electrons between the atoms and the
red dots are nonbonding electrons.) Hint: Since this is an organic
compound, nonbonding electrons are, in general, not shown in the line-
bond structural formula

Structures

Sir John Wilson School


• Names of compounds
• The names of organic compounds have two
parts: the prefix or stem and the end part (or
suffix)
• The prefix tells you how many carbon atoms
are present in the longest continuous chain in
the compound
• The suffix tells you what functional group is on
the compound
