(a)
Interpretation:
The Lewis structure of ammonia molecule has to be drawn.
Concept introduction:
Lewis structure: It is the representation of bonding between atoms in a molecule that satisfies the octet rule of valence electrons. The lone pairs are also shown in the molecule. The electron is represented as dot.
(b)
Interpretation:
Ammonia molecule whether possess polar bond have to be identified.
Concept introduction:
Polar covalent bond involves an unequal sharing of electrons between two bonded atoms; it creates a partial separation of charge and a dipole moment.
Covalent bonds are polar, if there is a difference in electronegativity between the bonded atoms.
(c)
Interpretation:
Ammonia molecule is whether a polar one has to be identified.
Concept introduction:
Polar covalent bond involves an unequal sharing of electrons between two bonded atoms; it creates a partial separation of charge and a dipole moment.
Covalent bonds are polar, if there is a difference in electronegativity between the bonded atoms.
(d)
Interpretation:
Ammonia molecule is whether soluble in water has to be identified.
Concept introduction:
‘Like dissolves like’ principle said that polar compounds including ionic compound should be more soluble in polar solvent. Likewise, non-polar compound should be more soluble in non-polar solvent. Other hand, compounds with similar intermolecular force capability to soluble in one another because solute-solvent interactions are similar signification to the solute-solute interaction.
