Final answer:
Among the given options, Ammonium chloride (NH4Cl) is the compound that features both ionic and covalent bonding, with the ionic bond being between the ammonium ion and chloride ion, and covalent bonds within the ammonium ion itself. so, none of the options are correct.
Step-by-step explanation:
The compound that utilizes both ionic and covalent bonding among the options given is Ammonium chloride (NH4Cl). This compound is not listed explicitly but considering the teaching material where ammonium compounds have been mentioned, like NH4+ with CO32− to be ionic, NH4Cl similarly has ionic characteristics due to the ammonium ion and chloride ion. However, within the ammonium ion itself, the nitrogen and hydrogen atoms are connected by covalent bonds.
Compounds like NaCl exhibit pure ionic bonding as they are formed by the transfer of electrons between a metal and a nonmetal. In contrast, molecules like H2O, CO2, and CH4 are purely covalent compounds because they consist of nonmetals sharing electrons.
The compound that utilizes both ionic and covalent bonding is NaCl (sodium chloride). NaCl is an ionic compound that forms when the metal sodium (Na) transfers one electron to the non-metal chlorine (Cl). This transfer of electrons creates oppositely charged ions, Na+ and Cl-, which then attract each other through ionic bonding.
