Why is the melting point of an element lower than its boiling point? Why are group 1 melting points and boiling points lower than those of group 2 elements? Why do ionic compounds have high melting points? Explain very briefly why the boiling point of H2O is higher than that of...
Does HF or HCl have a higher boiling point? Explain why. If branching increasing stability in alkanes (will have lower heat of combustion), then how does an increase in branching lead to lower boiling points? Rank the following in increasing boiling point and exp...
There are over 1200 hydrocarbons in tobacco smoke, including alkanes, alkenes, alkynes, alicyclic hydrocarbons, monocyclic aromatic hydrocarbons, and polycyclic aromatic hydrocarbons (PAHs). Over 500 tobacco smoke PAHs are known, many of which have been extensively studied because of their link to pot...
Why do corn cobs have long tassels ? View Solution Why do animals consume more energy as compared to plants View Solution Why do alcohols possess higher boiling points as compared to those of corresponding alkanes ? View Solution Why do He and H2 shows exceptional behaviour as compared to res...
will have a higher melting point than a linear alkane of the same molecular weight due to the effeciency of packing in the former: linear alkanes pack much more closely together than branched alkanes, which means the shared surface area is larger (or, the average distance between molecules is...
In terms of structure, explain why salt has a higher melting point than sugar.Explain why alcohols have higher boiling points as compared to their corresponding alkanes. Use appropriate chemical equations to explain this phenomenon.Explain how th...
This can be useful information as a molecule's polarity is responsible for many of its physical and chemical properties, such as boiling point, melting point, solubility and acidity. Polar molecules tend to interact favourably with other polar molecules as dipole moments can align,...
