The list of some substances is given below. HCl, H2O, Cl2, NaBr, CH4,

1.	The list of some substances is given below. HCl, H2O, Cl2, NaBr, CH4, NH3, N2, O2, CaO, HF, I2 and Br2. From the list above choose the substance / substances.i) Which have only ionic bond in the molecules?ii) Which has a triple covalent bond in its molecule?iii) Which are solids?iv) Which has a double covalent bond in its molecule?v) Which is non-polar covalent liquid?
Answer» i) NaBr, CaO have only ionic bond in the molecules, ii) N₂ has a triple covalent bond in its molecule (N ≡ N ) iii) Generally ionic compounds are solids. So NaBr, CaO are solids. I₂ being a covalent compound still it is solid. iv) O₂ has a double covalent bond in its molecule (O = O). v) The non-polar covalent liquid is Br₂.

Answer»

i) NaBr, CaO have only ionic bond in the molecules,

ii) N₂ has a triple covalent bond in its molecule (N ≡ N )

iii) Generally ionic compounds are solids. So NaBr, CaO are solids. I₂ being a covalent compound still it is solid.

iv) O₂ has a double covalent bond in its molecule (O = O).

v) The non-polar covalent liquid is Br₂.
