What is the best reason for the difference in properties of LiCl and C_(6)H_(14)O LiCl and C_(6)H_(14)O have different atomic masses. Cl and O belong to different groups of the periodic table. One compound is ionic, and the other is metallic. One compound is covalent, and the other is ionic.

The best reason for the difference in properties of LiCl and $C_{6}H_{14}O$ is that one compound is ionic, and the other is covalent.<br /><br />LiCl (lithium chloride) is an ionic compound, while $C_{6}H_{14}O$ (hexane-1,6-diol) is a covalent compound. The difference in their properties is due to the nature of the bonding between the atoms in each compound.<br /><br />In ionic compounds like LiCl, the atoms are held together by strong electrostatic forces of attraction between positively charged ions (cations) and negatively charged ions (anions). This results in high melting and boiling points, good electrical conductivity in the molten state or when dissolved in water, and the ability to form crystalline structures.<br /><br />On the other hand, covalent compounds like $C_{6}H_{14}O$ are held together by the sharing of electrons between atoms. This type of bonding results in lower melting and boiling points, poor electrical conductivity, and the inability to form crystalline structures.<br /><br />Therefore, the key difference in the properties of LiCl and $C_{6}H_{14}O$ is that one is an ionic compound and the other is a covalent compound.
