A set of organic compounds with the same fuctional group
22 of 28
Name 2 properties of a homologous series?
The genral formula and they show trends in physical properties
23 of 28
Will a branched molecule have a lower of high boiling/melting boiling point than an unbranched molecules?
Lower, because molecules are less closely packed
24 of 28
What is an isomer?
Molecules that have the same molecular formula but whose atoms are arranged differently
25 of 28
What's a structural isomer?
Structural isomers have the same molecular formula but different structural formula
26 of 28
What are the three types of structural isomerism and explain them?
Postional isomerism: the functional group is attached to the main chain at different points, functional group isomerism:different functional group, Chain isomerism:different arrangement of hydrocarbons
27 of 28
If an isomer is branched, what is it called?
Chain-branching
