intermolecular force: dipole-dipole
• 2 polar molecules (determined by electronegativity) • positive and negative ends attract
intermolecular force: London dispersion
• non polar molecules • electrons distort briefly and will be temporarily be dipole • very weak bond
intermolecular force: hydrogen bonding
• O, N, F bond with Hydrogen • H from one molecule bonds with the a lone pair of electrons on another molecule • very strong
effect of branching on boiling points
• long chain=increased boiling point • more branching = decreased boiling point
effect of intermolecular force on boiling point
hydrogen bonding=increased boiling point
polarity effects on solubility
• like dissolves like • polar dissolves polar • non polar dissolves non polar
define hydrocarbons
compounds composed of only carbon and hydrogen
functional group: alkane
single bond
hybridization of alkanes
sp3
functional group: alkenes
double bond
hybridization of alkenes
sp2
functional group: alkynes
triple bond
hybridization of alkynes
sp
what does the prefix “cyclo-“ mean?
the structure forms a ring
understand naming alkanes!!
• prefix = number of carbons • suffix = -ane • lower numbers are better and use alphabetical order
functional group: alcohol
-OH
functional group: ether
-O-
functional group: aldehyde
-COH
functional group: ketone
-CO
functional group: carboxylic acid
-COOH
functional group: amine
-NH2 - NO OXYGEN
functional group: amide
• NH2O • DO HAVE OXYGEN
functional group: Nitriles
-CN
define Acid/Base reaction
exchanging of a proton
