(a) ' Stability of a crystal is reflected in the magnitude of its melting point . Comment (b) The melting points of some compounds are given below : water = 273 K ,Ethyl alcohal= 155.7 K , Diethyl ether = 156.8 K , Methane = 90.5kK what can you say about the intermolecular forces between these molescular ?

Higher <a href="https://interviewquestions.tuteehub.com/tag/melting-1093090" style="font-weight:bold;" target="_blank" title="Click to know more about MELTING">MELTING</a> point of water than alcoholshows that hydrogen bonding in <a href="https://interviewquestions.tuteehub.com/tag/ethyl-976035" style="font-weight:bold;" target="_blank" title="Click to know more about ETHYL">ETHYL</a> alcohol molecules is not are strong as in water molecules. Diethyl ether is a <a href="https://interviewquestions.tuteehub.com/tag/poler-7708130" style="font-weight:bold;" target="_blank" title="Click to know more about POLER">POLER</a> molecule. The intermolecular forces present in them are dipolediple attraction. Methane is a non-polar molecular.The only forces present in them are the weak van der Waal's forces ( London dispersion forces).</body></html>
