Question

what type of interactions hold the molecules together in a polar molecular solid?​

Answer 1

Molecule are held together by following vender wall force and the interaction are :-

Hydrogen bond :--- one the strongest interaction between two molecule .

Dipole - Dipole interaction :-- it is second most strongest interaction between two dipole molecule .formation of covalent bond .

Dipole Non - Dipole interaction :-- it is weaker then Dipole - dipole and are formed by the interaction of one Dipole and another non Dipole molecule .

london /disprson interaction :-- it is one of the weakest interaction between two molecule and it is easily broken by the presence of small amount of heat .

interaction due to charge between two molecules are electrostatic interactions .
