Document Summary
For friday: skim (15 min) pgs 58-77, on line quiz 4, pre-lecture video on functional groups. A compound is : a substance consisting of two or more different atoms, in specific proportions, bonded together in a specific pattern. A shorthand way to represent the types and numbers of different atoms present in a molecule. Isomers: molecules with the same molecular formula, but a different arrangement of atoms: types of isomers, structural isomers, geometric isomers-involve a c-c bond, cis isomer: the two x"s are on, trans isomer, optical isomers (ex. 1, oxygen a#= 8, am= 16) 342 daltons: c254h377n65o75s6= 5727 daltons (3048+377+910+1200+192) How much nacl would you need to make 1 liter of a 1 molar solution? (sodium a#=11, am= 22; chlorine a#=17, am=34; oxygen a#=8, am=16) 56 g (first find molecular weight, in this case (22+34=56) then (56 x 1)
