Water is said to belong to the covalent category. In other words, water is made up of covalent bonds and not ionic bonds. If we look at the structure of water, then we will notice that the hydrogen atoms tend to share electrons with the oxygen atom making it covalent.

Water is a Polar Covalent Molecule Water (H2O), like hydrogen fluoride (HF), is a polar covalent molecule. When you look at a diagram of water (see Fig. 3-2), you can see that the two hydrogen atoms are not evenly distributed around the oxygen atom.

Water is a polar molecule. It has a permanent dipole. The O atom has a partial negative charge, and the H atoms have a partial positive charge. When you place an ionic substance in water, the water molecules attract the positive and negative ions from the crystal.

4 Answers. in solid state pcl5 prefer to exist as oppositely charged ions like [pcl4]- and [pcl6]- as the ionic bonding enhances the crystalline nature . also [pcl4]- is tetrahedral , while [pcl6]- is octahedral . these structure fit well into each other providing extra stability to solid structure .

The solubilities of C2H6 and C3H8 exhibit quite similar behavior with respect to added NaCS. The solubilities of these two gases are very low in pure water and are found to be nearly independent of NaCS concentration over a concentration range of 0-0.4 mol NaCS/kg H2O.

Ethanol (ethyl alcohol, C2H5OH) dissolves in water because the partial charges on the H and O atoms in the molecule interacts strongly with the partial charges on the atoms in water.
