Intro to Intermolecular Forces Flashcards
hydrogen bond acceptor
lone electron pair in a polar bond
hydrogen bond donor
H in a polar covalent bond
rank h bonds, vdw, and covalent bonds from shortest to longest
covalent, h, vdw
enthalpy
realized from making and breaking covalent bonds or ionic interactions can calculate form bond energies
delta G plus sign thing
speed at which equilibrium is approached
delta G
determines the equilibirum that is eventually reached
1 kcal
4.18 kJ
what makes a molecule polar
unequal sharing of electrons in covalent bonds
dipole moment
charge x separation
hydrogen bonds are part
electrostatic and part covalent
why are the distance and angle of h bonds strained
partial covalent character
strongest H bonds form at
180
distance two atoms in h bond
2.9 a
distance betewen two atoms in wdv
3.4 A
rank IMFs
london (4)
