Lewis Structures and Formation of Molecules

Sure, I can help you with that! Let's start by creating Lewis structures for the given compounds and then discuss the mechanisms of their formation.

(a) Bromine (Br2) The Lewis structure for bromine (Br2) can be represented as follows: - Each bromine atom contributes 7 valence electrons. - The bond between the two bromine atoms is a single covalent bond, sharing two electrons.

The Lewis structure for bromine (Br2) is: ``` :Br - Br: ``` The formation of the Br2 molecule occurs through a process called covalent bonding, where the two bromine atoms share a pair of electrons to achieve a stable electron configuration.

(b) Hydrochloric Acid (HCl) The Lewis structure for hydrochloric acid (HCl) can be represented as follows: - The hydrogen atom contributes 1 valence electron, and the chlorine atom contributes 7 valence electrons. - The bond between hydrogen and chlorine is a single covalent bond, sharing two electrons.

The Lewis structure for hydrochloric acid (HCl) is: ``` :H - Cl: ``` The formation of the HCl molecule also occurs through covalent bonding, where the hydrogen and chlorine atoms share a pair of electrons to achieve stability.

Mechanism of Formation

The formation of molecules in both cases (a) and (b) involves the sharing of electrons through covalent bonding. Covalent bonding occurs when atoms share electrons to achieve a full outer shell of electrons, typically 8 electrons for most atoms. This sharing allows each atom to attain a stable electron configuration, similar to the noble gases.

In the case of bromine (Br2), the two bromine atoms share a pair of electrons to form a single covalent bond, resulting in the formation of the Br2 molecule.

Similarly, in the case of hydrochloric acid (HCl), the hydrogen and chlorine atoms share a pair of electrons to form a single covalent bond, leading to the formation of the HCl molecule.

This mechanism of electron sharing and covalent bonding is fundamental to the formation of many different molecules and compounds.
