Ionic compounds in general do not possess: This question has multiple correct options. Organic compounds don't have higher melting and boiling point, inorganic compound have. Most pure substances - including most organic compounds - have a melting point under the right conditions but it is not true that all substances have a melting point. Organic compounds have low melting and boiling points, are volatile and slow reacting, covalent compounds.Unlike inorganic compounds, they react in vigorous conditions like high temperature, pressure, and in the presence of catalysts. This includes some organic substances. On the other hand, organic compounds are made of comparatively weak covalent bonds, which is the cause of their low melting and boiling point. Inorganic compounds are mostly made of strong ionic bonds, which give them a very high melting and boiling point. The key is not whether they are organic or inorganic but the bonding type. The best that I have been able to determine is that it has to do with the rigidity of the rings. Ionic compounds [which are mainly non-organic] have high melting points and boiling points. The highest melting and boiling points are for butanoic acid which has strong hydrogen bonds. It's because of the difference in chemical bonds. Ionic compounds usually have high melting points because the electrostatic forces holding the ions (ion-ion interaction) are much stronger. View Answer. Some compounds are not thermally stable enough to melt, and these decompose instead when heated. Melting and boiling points of alkyl halide compounds are much higher than alkanes. MEDIUM. Assertion Stronger intermolecular interactions result in higher melting points. MEDIUM. Now we discuss some problems by comparing different elements and compounds which have different melting and boiling points. View Answer. Propane has the lowest melting and boiling points and the weakest interactions. Covalently bonded compounds, which includes most organic compounds and many non-metal compounds have low melting points and boiling points. The next lowest melting and boiling points are for bromoethane and diethyl ether, which both have dipole-dipole interactions, the next strongest intermolecular forces. Electrovalent compounds have a high melting point and boiling point while covalent compounds have low melting and boiling points. Ionic compounds have high melting and boiling points because there is a strong electrostatic force of attraction between the oppositely charged ions and hence a large amount of energy is required to break the strong bonding force between ions. When relative molecular mass of organic compound increases, melting and boiling points also increase. In organic compounds the presence of polarity, or especially hydrogen bonding, generally leads to higher melting … With the rings locked into certain conformations, the molecules are able to come into closer contact, as the movement of the chains in the non ring compounds can clear a larger around the molecules.
