Stereochem Flashcards
(21 cards)
An instrument that allows plane polarized light travel through a sample tube containing an organic compound
Polarimeter
____ object or moecuke is not superimposable on its mirror image making it ____ center when there are 4 diff atoms around
Chiral
Isomers differing only in their 3D arrangements
Stereoisomers
Optical isomers are stereoisomers that are nonsuperimposable (they mirror each other)
Enantiomers
Optical isomer that are NOT mirror image of each other
Diasteriomers
Chrial molecule with chiral carbon containing plane of symmetry or center of symetry that are optically inactive
Meso compound
Thermal decomposition of alkanes in absence of air
Cracking
Lewis acid
AlCl3
Electron loving meaning electron dificient and would accept a pair of electrons meaning they are (+) charged ions
Electrophile
These are ions that are nucleus living typically having a negative (-) charge
Nucleophile
They provide electrons for making a new covalent bond
Nucleophile
They accept electrons in chemical reaction
Electrophile
They act as the lewis acid
Electrophile
Lewis Acid electron pair
ACCEPTOR electrophile
Lewis base electron pair
Donor nucleo
Major sources if alkanes are
Natural gas and petroleum
___ is a complex mixture of compound mostly alkanes and other hydrocarbon
Petroleum
The distillation of crude petroleum where it separates into various fraction is called
Refining
The larger the molecular weight, the _____ the BP
Higher
For compounds with the same MW, the larger the Surface Area, the _____ the boiling point
Higher
Imcomplete combustion of alkanes produces
CO carbon monoxide
