Bangsa
100
two identical atoms are locked on opposite sides of the double bond
trans
100
two identical atoms are locked on same sides of the double bond
cis
200
Have same molecular formula but a different geometric arrangement, in which rotation around a carbon bond is restricted.
Geometrical isomerism
200
trans 1,2-difluoroethene
300
A form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space
stereoisomerism
300
draw cis-3-hexene
400
the basic carbon skeleton remains unchanged, but important groups are moved around on that skeleton
Position isomerism
400
isomers arise because of the possibility of branching in carbon chains
Chain isomerism
500
The two different molecules are mirror of each other and cannot be superimposed
Optical isomerism or enantiomers
500
The carbon atom with the four different groups attached
