melting point and boiling point of organic compounds

Metals have metallic bond strengths, which is intermediate to that of covalent and ionic bonds. Therefore in general, metals have boiling and melting points in between to that of covalent and ionic compounds..

The compounds containing hydrogen bonds have high melting and boiling points. Due to hydrogen bonding, the intermolecular force of attraction in the compound becomes large. Consequently, larger energy is required in separating these molecules befor..

Melting Points and Boiling Points - The melting and boiling points of group 14 elements are much higher as compared to those of group 13 elements. Explanation: It is because the atoms of group 14 can form four covalent bonds with..

The melting and boiling points of group 14 elements are much higher as compared to those of group 13 element..

Metals have high melting and boiling point - Tungsten has the highest melting point where as Hg has low boiling point. Na and K have low melting points..

Melting points (except for antimony and bismuth) and boiling points increase on going down the group from N to B..

The melting and boiling points of elements are determined by the inter-atomic or inter-molecular forces between the constituent particles in the lattice and liquid state respectively. It is difficult to predict the variation in melting and boiling ..

The melting and boiling points increase with the increase in atomic number as we go down the group. Explanation: When we move down the group, the molecular size increases. As a result, the magnitude of the van der Waals forces also increases with increase in atomic nu..

All alkali metals are soft and have low melting and boiling points. As alkali metals have only one valence electron per metal atom, the energy binding the atoms in the crystal lattice of the metal is low. Consequently, the metallic bonds in these metals are not very s..

The melting and boiling points of alkali metal halides are high due to their ionic nature. For a given alkali metal ion the melting and boiling points decrease in the order F > Cl > Br > I. For the same halide ion, the melti..
