The covalent bonds connecting monomer units in proteins can be formed by the removal of a water molecule. a reaction referred to as a reaction.

A dehydration reaction

The metal is named first

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
