Answer: covalent compounds
Group VA hydrides (like NH3, PH3, AsH3) are molecular substances with covalent bonds between the group 15 atom and hydrogen. They are not ionic because the electronegativity difference is not large enough for complete electron transfer.
Q2. Water is a kind of \( _{-1-} \) oxide.
