Which of the following compounds is an example of an electrovalent bond?
A
NaCl (sodium chloride)
B
CO2 (carbon dioxide)
C
H2O (water)
D
CH4 (methane)
correct option: a
An electrovalent bond, also known as an ionic bond, is formed when there is a transfer of electrons from one atom to another.
In the case of sodium chloride (NaCl), sodium (Na) donates an electron to chlorine (Cl), resulting in the formation of ions (Na+ and Cl-) that are held together by electrostatic forces.
This transfer of electrons leads to the creation of oppositely charged ions, and the attractive force between them forms the electrovalent or ionic bond. In contrast, options (CO2), (H2O), and (CH4) involve covalent bonds where electrons are shared between atoms.
