Give 2 reasons why derivative of hydrazine (which is hydrazone) is crystalline solids and not liquids?

Question

hello, i hope u can understand the question. i have a synthesis problem over here, where i got a hydrazone product. It is given that it is solid. but i have to give 2 reasons why the product was solid and not liquid...i know it has to do something with mp or bp..but i dont know what to write????

please helpp mee!!

Answer 1

The product is solid at room temperature, meaning it has a relatively high melting point. This is a result of relatively strong forces between the molecules. This can caused by having a large molecule, a polar molecule, or both. If the molecule is polar, dipole-dipole attractitions result in a predictable lattice structure. If the molecule is simply large, it is easy for London forces to induce temporary dipoles that strengthen the bonds between molecules. These may be the two factors you are looking for, but you'll need to confirm that your molecule is polar.
