Nuclear binding energy is necessary to overcome which of the following a. einstain's mass defect b. kinetic energy of the nucleus c. repulsion of the protons d. weak nuclear force

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   

The correct answer is "false"
