2.21 Explain why hydrogen fluoride (HF) has a higher boiling temperature than hydrogen chloride (HCI) (19.4°C vs. -85°C), even though HF has a lower molecular weight
Part A H,0 (100°C) has a higher boiling point than CH, OH (65°C). There are more hydrogen bonds between water molecules than between alcohol molecules. There are less hydrogen bonds between water molecules than between alcohol molecules. CH, OH has the higher molecular mass than H,O. There are no hydrogen bonds between alcohol molecules while there are plenty of them between water molecules. O Submit Previous Answers Request Answer X Incorrect; Try Again; 2 attempts remaining Part B H,O (100°C)...

C The boiling point of H,O is much higher than the boiling point of HS. H2O is a molecular compound, while HS is an ionic compound. H2O is a polar molecule, so the attractions between the molecules are stronger than those between nonpolar H2S molecules. H2O has strong hydrogen bonds between its molecules, and HS molecules cannot form hydrogen bonds. The dispersion forces between the H2O molecules are much stronger. d The boiling point of CH,O is much higher than...
Why does benzene have a much higher boiling point (80。c) than hexane (69。c), even though they have the same number of carbons? A) Benzene is much more polar than hexane which enhances the attractive forces between molecules and raises the boiling point. B) Benzene has fewer hydrogens than hexane. C) Benzene is planar and has delocalized electron density which increases the attractive forces between molecules and raises the boiling point. D) Benzene can covalently bond to another benzene molecule which...
Explain why acetic acid has a higher boiling point than ethyl alcohol ?
The boiling points of t-butyl methyl ether (2-methoxy-2-methylpropane) and n-butyl methyl ether (1-methoxybutane) differ by 16 degrees (71 and 55 °C), even though they have the same molecular weight. Draw the two structures below: The boiling points of t-butyl methyl ether (2-methoxy-2-methylpropane) and n-butyl methyl ether (1- methoxybutane) differ by 16 degrees (71 and 55 °C), even though they have the same molecular weight. Draw the two structures below: Which compound has the higher boiling point and why? 1-methoxybutane has...
Please show your work The reaction of 1,3-pentadiene with hydrogen chloride (HCI) gives the product shown below (as a racemate). However, the reaction with deuterium chloride (DCI) produces two products, A and B (also as racemates), and the ratio of these is temperature dependent. Which product, A or B is favored at low temperatures (0°C) and What happens to the ratio at higher temperatures (40°C)? Explain these in terms of kinetic vs thermodynamic control. (20 points d. How might you...
