Chemists are able to identify the intermolecular forces present in a covalent compound. Answer Save. Reactions of alkylphenylacetylenes with antimony pentachloride in carbon tetrachloride give the corresponding dichloroalkenes in 20–55% yields, (Z)-addition predominating. When silicon dioxide melts all the covalent bonds in the giant structure must be broken. Inorganic Chemistry 1963, 2 (3) , 437-441.

Intermolecular forces can be defined as the attraction between molecules. It has a 3s and three 3p orbitals, so it must use one of its 3d orbitals to form the fifth bond.These orbitals are hybridized to form five sp3d orbitals and thus form a trigonal bipyramid. The P atom needs five orbitals to form the five P-Cl bonds .
