(A) H2
(B) 02
(C) NaCl
(D) None of these​

Answer 1

Answer:

A heteronuclear molecule is a molecule composed of atoms of more than one chemical element. For example, a molecule of water (H2O) is heteronuclear because it has atoms of two different elements, hydrogen (H) and oxygen (O).

Explanation:

Answer 2

Among the given species, the heteronuclear molecule is NaCl (Option c)

• A heteronuclear molecule is a molecule that consists of atoms belonging to more than one element.
• While the molecules which are composed of only one element are termed as homonuclear.
• In the given case, H₂ and O₂ molecules consist of only H and O atoms respectively whereas the NaCl molecule consists of Na and Cl atoms, hence it is heteronuclear.
