Mercury
Control of Transboundary Movements of Hazardous Wastes and Their Disposal
Basel Convention
rate at which temperature changes with altitude
lapse rate
protocol on the control of greenhouse gases
Kyoto Protocol
phasing out of CFCs
Montreal Protocol #13
follow up to the Kyoto Protocol
Copenhagen Accord
meeting where persistent organic pollutants were phased out
Stockholm Convention
who coined the term “isomers”
Jans Jacob Berzelius
Reacted carbon disulfide (inorganic) to produce acetic acid (organic)
Adolph Wilhelm Hermann Kolbe
discovered the structure of benzene
August Kekule
Octet rule and Lewis structures
Gilbert Lewis
postulated that reaction behavior is due to the movement of electrons
Robert Robinson
structures focused on the delocalization of electrons, e- are shared across nuclei
Resonance structures
electrons are localized in covalent bonds
Lewis structures
what does iso- mean
all except one carbon form a continuous chain
what does sec- mean
the substituent is attached to a secondary carbon
what does tert- mean
attached to a tertiary carbon
what does neo mean
all but two carbons form a continuous chain
Who produced the Wholer synthesis? using ammonium cyanate to form urea
Friedrich Wohler
Who suggested the concept of resonance?
Linus Pauling
Constitutional isomers
elements are not bonded similarly
Stereoisomers
different orientation
