In an acid molecule, an ionizable hydrogen atom is connected to the molecule by a(n) covalent bond while a hydrogen atom that is not ionizable is connected by a(n) covalent bond.

In an acid molecule, both ionizable and non-ionizable hydrogen atoms are connected to the molecule by covalent bonds. The difference between the two lies in their position within the molecule and their ability to dissociate.

1. Ionizable Hydrogen: This is a hydrogen atom that is attached to a highly electronegative atom (like oxygen, nitrogen, or a halogen) in the molecule. Because of the high electronegativity of these atoms, they pull the shared electrons in the covalent bond closer to themselves. This makes the hydrogen atom slightly positive, allowing it to be easily ionized (i.e., it can easily lose its electron and become a hydrogen ion, H+).

2. Non-Ionizable Hydrogen: This is a hydrogen atom that is attached to a less electronegative atom. The shared electrons in the covalent bond are not pulled as strongly towards the other atom, so the hydrogen atom is not as easily ionized.

In both cases, the hydrogen atoms are connected to the rest of the molecule by covalent bonds. The difference in ionizability is due to the electronegativity of the atoms they are bonded to, not the type of bond itself.
