Which member of the following pairs has the stronger intermolecular dispersion forces:
Br2 or O2
CH3CH2SH or CH3CH2CH2SH
CH3CH2CH2Cl or (CH3)2CHCl
and if possible could you explain how you found it.

compounds with more H-bonds (can only be Hydrogen bonded with either Flourine, Oxygen, and Nitrogen) Those have stronger intermolecular forces. Anything with higher electronegativity has stronger forces. Also Dipole-Dipole must occur (polar).
O2 is stronger more electronegativity (shorter bond=stronger Lattice energy)
CH3CH2CH2SH stronger contains more electrons
CH3CH2CH2Cl stonger

Br2
CH3CH2CH2SH
These two above have more electrons than their counterparts and can make better dispersion forces
CH3CH2CH2Cl
This one is a more 'linear' molecule than its nearly spherical couterpart and it can have more points of contact with other moluecules so that it has better bonds
