(a)
Interpretation:
Whether the bonds are polar or not and bond angle of Silane (SiH4) should be determined along with whether the molecule is whole polar or not.
Concept introduction:
- The bond is polar if there is greater electronegativity difference between the two bonded atoms.
- The bond angle is dependent upon the molecular geometry of molecule
- The molecule is polar if there are polar bonds present in them and the dipole of the bonds does not cancel each other or there is a net dipole moment associated with the molecule.
(b)
Interpretation:
Whether the bonds are polar or not and bond angle of Hydrogen selenide (H2Se) should be determined along with whether the molecule is whole polar or not.
Concept introduction:
- The bond is polar if there is greater electronegativity difference between the two bonded atoms.
- The bond angle is dependent upon the molecular geometry of molecule
- The molecule is polar if there are polar bonds present in them and the dipole of the bonds does not cancel each other or there is a net dipole moment associated with the molecule.
(c)
Interpretation:
Whether the bonds are polar or not and bond angle of Phosphine (PH3) should be determined along with whether the molecule is whole polar or not.
Concept introduction:
- The bond is polar if there is greater electronegativity difference between the two bonded atoms.
- The bond angle is dependent upon the molecular geometry of molecule
- The molecule is polar if there are polar bonds present in them and the dipole of the bonds does not cancel each other or there is a net dipole moment associated with the molecule.
(d)
Interpretation:
Whether the bonds are polar or not and bond angle of Silicon tetrafluride (SiF4) should be determined along with whether the molecule is whole polar or not.
Concept introduction:
- The bond is polar if there is greater electronegativity difference between the two bonded atoms.
- The bond angle is dependent upon the molecular geometry of molecule
- The molecule is polar if there are polar bonds present in them and the dipole of the bonds does not cancel each other or there is a net dipole moment associated with the molecule.
(e)
Interpretation:
Whether the bonds are polar or not and bond angle of Oxygen diflouride (OF2) should be determined along with whether the molecule is whole polar or not.
Concept introduction:
- The bond is polar if there is greater electronegativity difference between the two bonded atoms.
- The bond angle is dependent upon the molecular geometry of molecule
- The molecule is polar if there are polar bonds present in them and the dipole of the bonds does not cancel each other or there is a net dipole moment associated with the molecule.
(f)
Interpretation:
Whether the bonds are polar or not and bond angle of Formaldehyde (H2CO) should be determined along with whether the molecule is whole polar or not.
Concept introduction:
- The bond is polar if there is greater electronegativity difference between the two bonded atoms.
- The bond angle is dependent upon the molecular geometry of molecule
- The molecule is polar if there are polar bonds present in them and the dipole of the bonds does not cancel each other or there is a net dipole moment associated with the molecule.
