9. Chloroform (CHCL3) was one of the first anesthetics used in medicine. The Chloroform molecule contains 26 valence electrons total. How many of these valence electrons are part of covalent bonds?

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   

Answer(true);
