Core Organic Chemistry Flashcards
What is Avagadros law?
Equal volumes of gasses, at same temperature and pressure , contain the same number of particles
What is room temp and pressure?
1 atmosphere
298 kelvin (25+273)
Equation for gas volume at RTP
Gas volume = moles x molar volume (24dm3)
What is the ideal gas equation ?
Pressure x volume = moles x gas constant x temperature
(pV = nRT)
What is the gas constant ?
8.314J/mol-1
Define relative atomic mass
The weighted mean mass of an atom compared to 1/12 of the mass of carbon 12
Define percentage yield
The amount of product you actually have as a percentage of the amount you theoretically should have
Define atom economy
Mass of product desired as a percentage of the mass of product made
Define structural formula
Smallest amount of detail possible to show arrangement of molecule
Define Homologous
Series of organic compounds having the same functional group but with each successive member differing by CH2
What is the functional group?
Atoms or atom groups that affect the chemical properties of a organic compound
Define isomerism
Compounds with the same molecular formula are arranged different ways
Define metallic bonding
Electrostatic attraction between metal cations and delocalised electrons
Why doesn’t metal shatter when hit?
Electrons can re-establish bonds in a new structure
