Hey guys can smone explain why polar bonds are stronger than nonpolar bonds

Are you sure that is true?

Can you provide data to support your statement?

Hey guys can smone explain why polar bonds are stronger than nonpolar bonds

Are you referring to bonds between atoms or attractions between molecules?

I got this from a book: Organic compounds are nonpolar, the attractive forces in their molecules are
weak. Therefore their melting and boiling points are less compared with inorganic compounds which are either polar or ionic.

This helped me to deduce that nonpolar bonds are weaker than polar bonds.

Please re-check your textbook, you are crossing some words, and making incorrect deductions.  Specifically, like LQ43: said, "in their molecules" and "between their molecules" are not synonymous terms.

Does this help?

 I think... what the book means is that most organic compounds have lower melting and boiling points than inorganic compounds because their atoms are bonded by nonpolar bonds which are weaker than the bonds (polar and ionic) between the atoms of the inorganic compounds.

I would change your wording slightly

what the book means is that most organic compounds have lower melting and boiling points than inorganic compounds because their molecules are linked by nonpolar bonds which are weaker than the bonds (covalent and ionic) between the atoms within of the  inorganic molecules.

Note: the atoms in a hydrogen fluoride molecule are bonded by a covalent bond. This bond is highly polar because fluorine is the most electronegative element. Even though the HF molecule is highly polar, the material is still a gas at room temperature and pressure because the intermolecular forces are not strong enough to overcome the kinetic energy of the molecules and hence to cause a liquid or solid state to form.
