Which of the following compounds is an example of an electrovalent bond?
NaCl (sodium chloride)
CO2 (carbon dioxide)
H2O (water)
CH4 (methane)
Correct answer is A
NaCl, commonly known as sodium chloride or table salt, is an example of an electrovalent bond. Sodium (Na) donates one electron to chlorine (Cl), resulting in the formation of Na+ and Cl- ions, which are held together by the ionic bond.
