The compound having highest boiling point among the following is
Correct answer: D. HI(I)
- A. HF(I)
- B. HCI(I)
- C. HBR(I)
- D. HI(I)
Explanation
The boiling point of a compound is influenced by the strength of intermolecular forces. In this case, the compounds are hydrogen halides in the gaseous state. The strength of intermolecular forces generally follows the trendHF<HCl<HBr<HIThe strength of intermolecular forces increases as we move from HF to HI because the molecules have London dispersion forces, dipole-dipole interactions, and hydrogen bonding.Therefore, the compound with the highest boiling point among the options is HI (l) .

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
