Using the periodic table C8H18 has a covalent type of bond and it has a low melting point as its property.
Using the periodic table K2O has an ionic type of bond and it has malleable as its property.
Why is C8H18 have a covalent bond and K2O have an ionic bond?
- A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. So, in the case of C8H18 carbon and hydrogen are mutually sharing one or more pairs of electrons between them.
- An ionic bond can be formed after two or more atoms lose or gain electrons to form an ion. So, in the case of potassium oxide, it has valency +1 and combines readily with oxygen atomS forming K2O.
Why is C8H18 is likely to have low melting point properties and K2O likely to have malleable properties?
- The C8H18 has a low melting point because of its molecular compound. As energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound.
- K2O has malleable property because malleable is an ability to be hammered or pressed into shape without breaking or cracking. So, in the case of K2O as it is an ionic compound so it has unable to break because it is bonded with electrons.
