It undergoes heterolytic fission whereby the Cl atom gains both the shared electrons.

Explanation:

In aqueous medium, HCl dissociates to form H^+ and Cl^- ions. This happens when the covalent H-Cl bond breaks.

Reaction of HCl with NaOH will give Na^+ + Cl^(-) + H_2O.

Well, it breaks..............

Explanation:

We would describe the bond in hydrogen chloride as polar covalent, i.e. ""^(+delta)H-Cl^(delta-). Now hydrogen chloride is a room temperature gas, but the gas is VERY soluble in water to give hydrochloric acid, in which ionization is conceived to have occurred:

H-Cl(g) + H_2O(l) rarr H_3O^(+) + Cl^-

And we could represent the reaction of hydrogen chloride with sodium hydroxide as:

HCl(aq) + NaOH(aq) rarr NaCl(aq) + H_2O(l)

In aqueous solution, the (aq) represents the aquated ion, i.e. Na^(+)(aq) -=[Na(OH_2)_6]^+.
