HF
- C
H2O
- D
CsF

HCl
lonic bonds typically form between elements with significantly different electronegativities. In an ionic bond, one atom donates electrons (becomes a cation), while the other atom accepts electrons (becomes an anion).
Cesium fluoride is a substance composed of cesium and fluoride elements, which are different in type; cesium is metal and fluoride is a nonmetal. Considering that a metal and a nonmetal bonding results mostly in ionic compounds
Carbon dioxide is a molecule composed of carbon and oxygen, both nonmetals, forming covalent bonds by sharing electrons.
Hydrogen fluoride consists of hydrogen and fluorine, forming a polar covalent bond due to an unequal sharing of electrons, not an ionic bond.
Water, represented by the formula H2O, features polar covalent bonds where electrons are shared unequally between hydrogen and oxygen.
Cesium fluoride is an ionic compound. Cesium, a metal, transfers electrons to fluorine, a nonmetal, resulting in an ionic bond.
Hydrogen chloride (or hydrochloric acid in solution) consists of a polar covalent bond between hydrogen and chlorine, not an ionic bond.
