Why should the recrystallization solvent have a fairly low boiling point? Why does H2CO have a higher vapor temperature than CH3OH? Explain why alcohols have higher boiling points as compared to their corresponding alkanes. Use appropriate chemical equations to explain...
(a) Why do many organic compounds have low melting and boiling points? (b) Some organic compounds, like table sugar, do not have a boiling point. Suggest a reason why. Explain why C2H5OH and H3C-O-CH3 have different boiling points. Which one is higher?...
Comparing alkanes and silanes supports the idea thatmolecules that deform more easily melt more readily. See the attached picture - it displays sharp atoms, but their limits are of course fuzzy, more so for hydrogen. In both cases, the silane and alkane homologues have similar boiling temperature...
A Key Skill: How to Calculate Formal Charge The Four Intermolecular Forces and How They Affect Boiling Points Hidden Hydrogens, Hidden Lone Pairs, Hidden Counterions Partial Charges Give Clues About Electron Flow The Most Important Question To Ask When Learning a New Reaction00...
to draw proper Lewis structures for a molecule.To succeed in organic chemistry you absolutely need to be able to do this in your sleep.The Lewis structure should account for all the electrons around an atom, including the often-hidden lone pairs of electrons if applicable. Let’s have a ...
Explain why alcohols have higher boiling points as compared to their corresponding alkanes. Use appropriate chemical equations to explain this phenomenon. Briefly describe, why do elements in a given group have similar chemical properties? Give an atomic-level reason why ionic crystals a...
How do impurities affect the boiling point of a liquid? Why does cold metal conduct electricity better than warm metal? Explain why the melting point depresses and broadens when a sample is impure. Explain why alcohols have higher boiling points as compared to their corresponding alkane...
