Question

e the kinds of intermolecular forces that are present in a. 1 each element or compound. a. PH3 b. HBr c. CH3OH d. 12 44. In each pa pressure a a. CH40 b. CH C 45. Determ
Please explain

Answer 1

38. a) PH3 - dispersion forces and dipole-dipole forces

b) HBr - dispersion forces and dipole-dipole forces

c) CH3OH - dispersion forces , dipole-dipole forces and hydrogen bonding

d) I2 - only dispersion forces

46) a) CH3CH2CH2CH2CH3 and CH3CH2CH2CH2CH2CH3

YES.we predict a solution to be formed since the self-self intermolecular forces between CH3CH2CH2CH2CH3 molecules are londan forces and that is also true for CH3CH2CH2CH2CH2CH3

b) CBr4 and H2O

NO.the self-self forces in CBr4 are only londen forces,but.the self-self forces in H2O are london+dipole-dipole+hydrogen bonding.this means that when the water molecules are seperated to make room for the proposed solute,CBr4 some forces will have to be overcome which will not be compensated for by self other forces wuth a nonpolar CBr4 upon dissolution

c) LiNO3 and H2O

YES.we predict solution to be formed since the self-self intermolecular forces in these substance are similar

d) CH3OH and CH3CH2CH2CH2CH3

NO.the self-self IM forces in CH3CH2CH2CH2CH3 only london forces but the self-self IM forces in CH3OH are  london+dipole-dipole+hydrogen bonding
