alkenes
what is the functional group for alkenes
C=C bond
define a monomer
small molecules that join up to make long chain polymers
three types of structural isomerism
functional group isomerism, chain isomerism, position isomerism
two types of geometrical isomerism
cis isomers and trans isomers
what is a chiral carbon?
A carbon atom attached to four different groups of atoms
Are alkenes saturated or unsaturated
Unsaturated
define a polymer
long chain molecule made up from small molecules joined together
give the two isomers of C4H10
butane and 2-methylbutane
do geometrical isomers have the same or different physical and chemical properties
different
what is the definition of optical isomers
optical isomers are molecules that have the same molecular formula and structure, but are non-superimposable mirror images of each other.
general formula for alkenes
CnH2n
What are made from additional polymerisation other than polymers
Nothing
give the two isomers for C4H8
cyclobutane and butene
what types of compounds are geometrical isomers founded in
unsaturated and rings
what type of isomerism do optical isomers belong to
stereoisomerism
what types of bonds are found in the C=C bond
one sigma bond one pi bond
Why are addition polymers difficult to biodegrade
Chemically inert
what type of isomerism is but-1-ene and but-2-ene
position isomerism
why are geometric isomerism only present in alkenes
the double bond can't freely rotate
what is the same about optical isomers.
chemical properties
Give names of alkenes with 2-5 carbon and their molecular formula
ethene propene butene pentene
C2H4 C3H6 C4H8 C5H10
what is the monomer of pvc
vinyl chloride
give three isomers for C5H12
Pentane, 2-methylbutane, 2,2-dimethylpropane
definition of geometric isomerism
a type of isomerism that occurs due to the restricted rotation about the carbon double bond
what are a pair of optical isomers called
enantiomers
