Concept explainers
Interpretation: Among liquid bromine and the interhalogen compound, the compound having higher boiling point should be identified. Also the reason for the difference in boiling point should be stated.
Concept introduction: The set of repulsive and attractive force between molecules that result from the polarity between neighboring molecules is represented as intermolecular force. There are four types of intermolecular forces:
- Hydrogen bonding
- London dispersion force
- Ion – dipole force
- Dipole – Dipole force
Ion – dipole force is a strong intermolecular force as it contains both ionic and polar bonds.
Hydrogen bond: Hydrogen is bonded to strong electronegative atom like oxygen, nitrogen etc.
Dipole – Dipole: This force takes place between two polar compounds.
London dispersion force: This force is present in all compounds and is a weak force.

- Phosphine is a colorless toxic gas. It is a hydride of phosphorus. The chemical formula of this compound is PH3. On the other hand, Silane is also a colorless, pyrophoric, toxic gas with a sharp, repulsive smell. It is also a hydride of silicone. The chemical formula of this compound is SiH, According to the VSEPR model, provide comments, on the arrangement of electron pairs around PH, and SiHarrow_forwardBoron trifluoride (BF3) has no dipole moment (u = 0 D). Explain how this observation confirms the geometry of BF3 predicted by VSEPR theory.arrow_forwardSodium hydride, NaH, is available commercially as a gray-white powder. It melts at 800°C with decomposition. It reacts explosively with water and ignites spontaneously upon standing in moist air. Q) Write a Lewis structure for the hydride ion and for sodium hydride. Is your Lewis structure consistent with the fact that this compound is a high-melting solid? Explain.arrow_forward
- Why does CO2 have a linear shape with no dipole moment?arrow_forwardWhich is the most likely molecular structure for the nitrite (NO2-) ion?arrow_forwardIn a hydrogen molecule, the two hydrogen atoms are held together by a single bond with a bond energy of 436 kJ/mol of hydrogen. In other words, to break the H-H bonds in one mole of molecular hydrogen requires the expenditure of 436 kJ of energy. Using the balanced chemical equation for the formation of water from oxygen and hydrogen (shown above), and interpreting the stoichiometric coefficients as mole amounts, how much energy must be expended in breaking the H-H bonds? kJarrow_forward
