Compare and contrast the compounds ch4 and ph3 in terms of covalent bonding, molecular geometry (shape), and intermolecular forces. which substance would experience a stronger attraction between its molecules, and why?

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

C. They are held together by attractive forces
