Answer

Brief Explanations:

  1. Oil, made of non - metals hydrogen, carbon and oxygen, forms covalent bonds as non - metals share electrons. So it is a covalent compound.
  2. Cornstarch, also composed of hydrogen, carbon and oxygen (non - metals), has covalent bonds due to electron - sharing among non - metals. It is a covalent compound.
  3. Sodium chloride (NaCl) has a metal (sodium) and a non - metal (chlorine). Metals lose electrons and non - metals gain them to form ionic bonds. So it is an ionic compound.
  4. Sodium bicarbonate ($NaHCO_3$) has a metal (sodium) and non - metal groups. Sodium donates an electron to the bicarbonate group, forming an ionic bond. So it is an ionic compound.

Answer:

Oil: Covalent compound Cornstarch: Covalent compound Sodium chloride: Ionic compound Sodium bicarbonate: Ionic compound
