The steric number = the number of atoms bonded to the atom + the number of lone pairs the atom has. If the steric number is 4, the atom is sp3 hybridized. If the steric number is 3, the atom is sp2 hybridized. If the steric number is 2, the atom is sp hybridized.
Fluoxetine (Prozac) is a molecular (covalent) compound. Fluoxetine hydrochloride is the salt of that molecular compound, making it an ionic bond. The hydrochloride salt results from the addition of HCl to the free base (fluoxetine). The H+ is donated to the amine resulting in a quarternary amine (NH4+) with the associated Cl- ion forming the ionic bond and resulting in an ionic bond.
