Unit 2 : Systematic Carbon Chemistry Flashcards
What are single carbon-carbon bonds called
Saturated hydrocarbons
What are carbon-carbon double bonds called
Unsaturated hydrocarbons
What is the test for saturation
Bromine Water Test
How does the bromine water test work
The colour will rapidly disappear if there is a c=c bond present.
What is the shortened structural formula for ethane
CH3 CH3
What are isomers
Compounds with same molecular formula but different structural formula. They may be in different homologous series and have different physical properties.
What effect does the presence of -OH and -NH have on physical properties
They give a rise to hydrogen bonding between molecules
What effect does hydrogen bonding have on solubility
It increases solubility
What effect does hydrogen bonding have on boiling point
Increases boiling point
What effect does hydrogen bonding have on volatility
Decreases volatility as molecules are closer together
What effect does spatial arrangement of polar covalent bonds have on the physical properties of compounds
Polar covalent bonds in the correct arrangement gives a rise to permanent dipole-permanent dipole attractions
What effect does polar molecules have on solubility
More likely to be soluble in polar solvents
What effect does polar molecules have on boiling points
PD-PD attractions bring molecules closer together and raises the boiling point
