Explain the trend in boiling points between HF, HCl and HBr.

WebHydrogen bonds are formed in many compounds e.g., H2O, HF, N H3. The boiling point of such compounds depends to a extent on the strength of hydrogen bond and the number of hydrogen bonds. The correct decreasing order of the boiling points above compounds is (a) HF >H2O>N H3 (b) H2O>HF >N H3 (c) N H3>HF >H2O (d) N H3>H2O>HF Q. Web27 aug. 2024 · How do you determine boiling point and melting point? Calculate the change in boiling or freezing temperature using one the following formulas: ΔTf = Kf * m or ΔTb = Kb* m. Add the value obtained for ΔTb to the standard boiling point of the solvent (ex. 100 C for water) or subtract the value obtained for ΔTf from the standard freezing … WebHydrochloric acid solution 12 M; CAS Number: 7647-01-0; Synonyms: Hydrogen chloride solution; find Sigma-Aldrich-131683 MSDS, related peer-reviewed papers, technical … cst to west time
