Lesson 2 - More On Hydrocarbons Flashcards
there are how many types of hydrocarbons?
five
what is a saturated hydrocarbon?
it contains the maximum number of hydrogen’s, single bonds between all carbons
what is an unsaturated hydrocarbon?
it contains 1 or more double/triple bonds
what is an aliphatic hydrocarbon?
carbons arranged in chains
what is a cyclic hydrocarbon?
carbons arranged in rings
what is an aromatic hydrocarbon?
contains a benzene ring
what is a benzene
it is a cyclic 6-carbon ring of alternating single and double bonds (which gives it special properties)
if benzene is the parent chain use
“benzene” as the suffix
if benzene is a branch group use
“phenyl” as the branch name
what is a structural isomer?
a compound with the same formula but different arrangements of atoms and different properties
what is the other word for geometric isomers?
cis-trans isomers
what are geometric isomers?
it is when different groups of atoms are arranged around a double bond
the double bonds in a geometric can rotate. TRUE or FALSE?
FALSE. They cannot rotate
what is the criteria to be a geometric isomer?
each carbon in the double bond must be attached to 2 different groups
what is cis
larger groups are attached on the same side
what is trans
larger groups are attached on the opposite side
to name geometric isomers add “cis” or “trans” at the ________ of the name
beginning
