Molecular hydrides<\/strong><\/p>\n<p>Molecular hydrides are compounds formed when hydrogen combines with p-block elements. They are typically non-polar and have low boiling points. Some examples of molecular hydrides include water (H2O), ammonia (NH3), and methane (CH4).<\/p>\n<p>Ionic hydrides are compounds formed when hydrogen combines with electronegative elements such as oxygen, fluorine, and chlorine. They are typically highly polar and have high boiling points. Some examples of ionic hydrides include sodium hydride (NaH) and lithium hydride (LiH).<\/p>\n<p>Metallic hydrides are compounds formed when hydrogen combines with metals. They are typically non-stoichiometric and have variable properties.
