Intermolecular Forces

Question 1

london dispersion

Answer 1

present in ALL molecules, but only force b/w NP
attraction that becomes TEMPORARY diploles

Question 2

dipole dipole

Answer 2

only in polar molecules, force of attraction with PERMANENT dipoles
attraction b/w POS. and NEG. ends of dipoles

Question 3

hydrogen bonding

Answer 3

highly polar molecules
attraction b/w H ATOMS and LONE PAIRS on ADJACENT molecules

Question 4

diff b/w chem bond and imf

Answer 4

chem bond forms b/w atoms, imf forms b/w molecules, imf weaker and less energy required in their formation

Question 5

diff bw temporary and permanent dipole

Answer 5

temp: electrons are denser on one end of molecule
perm: when there is a pos. and neg. end from a polar bond
