Document Summary
Oice hours : mon 3:30-5:30 thurs 3-4pm fri 2-3pm. Read welcome email, course website, mastering chem instrucion, syllabus. Check to see if mastering chem login works. Odd labs start week 3 , even labs start week 2. 18 labs will meet on jan 11th. Recitaions on that day will be replaced on mon march 14th. Charges of same sign don"t want to be close = more energy. Is charge have opposite sign then if u decrease r , but increase in absolute value. But goes more to the negaive side = so smaller number. Imf are weaker than real chemical bonds b/c dist. b/tw molecules is larger than distance within the atoms. Noncovalent atracive interacions: london (dispersion) forces: intermolecular. Atracion b/tw posiive and negaive ends of induced(temporary) dipoles. Polarizaion: temporary shit in e- distribuion in a molecule. Occur b/tw all moleucles & are directly proporional with the # of e- in a molecule.
