Why melting points and boiling point for two C 61-1 14 isomers are given below. Explain and discuss why (CH 3)2CH(CH2)2CH3 has a lower melting point but higher boiling point?
The melting point and boiling point differences between the two isomers of C6H14, specifically (CH3)2CH(CH2)2CH3 (2-methylpentane) and its structural isomer, arise from their molecular structures and intermolecular forces. (CH3)2CH(CH2)2CH3 has a more branched structure, which results in less surface area for intermolecular van der Waals forces, leading to a lower melting point. However, the branching also reduces the packing efficiency, which can lead to a higher boiling point due to the increased energy required to overcome the weaker intermolecular forces in the liquid state.
How many isomers for dibromopropane?
There are two isomers for dibromopropane: 1,2-dibromopropane and 2,2-dibromopropane.
Is it true or false the boiling point one liter of water is different from the boiling point of two liters of water?
false
Why acetone lowers the boiling point of water whereas salt and sugar raise the boiling point and lower the melting point?
Acetone is a liquid with a boiling point lower than that of water; the other two are solids.
How is boiling point used in chemistry?
If you know a boiling point, you can separate two different liquids that are mixed together. If the two liquids have different boiling points, you can boil them both. One of the liquids will reach its boiling point before the other liquid and start to evaporate. One of the liquids will have evaporated and will be separated from the liquid with the higher boiling point. This is called distillation. Jarachia ~ x
What physical property is identical for the two isomers co C4H10?
The melting and boiling points are different. Butane has a melting point of 135.4K and 2-methylpropane [isobutane] has a melting point of 114K. The boiling point of Butane is 272.6K and isobutane @ 261K. It has to do with there structures. J
What are the two types of azeotropes?
The two types of azeotropes are minimum boiling point azeotropes and maximum boiling point azeotropes. Minimum boiling point azeotropes form at a boiling point lower than that of any of its components, while maximum boiling point azeotropes form at a boiling point higher than that of any of its components.
How many isomers for dibromopropane?
There are two isomers for dibromopropane: 1,2-dibromopropane and 2,2-dibromopropane.

What is the boiling point of ethyl chloride in degrees Fahrenheit Express your answer to two significant figures and include the appropriate units.?
This boiling point is 54,09 oF.
When a electric current is passed through water during the process of electrolysistwo gases are formed one gas has a boiling point of -183c and the other has a boiling point of -235c has a physica?
During the electrolysis of water, two gases are produced: hydrogen and oxygen. Hydrogen, which has a boiling point of -253°C, is the gas with the lower boiling point, while oxygen, with a boiling point of -183°C, is the gas with the higher boiling point. This physical property highlights the distinct characteristics of the two gases produced during the process.
What two factors affect the boiling point of water apex?
The two main factors that affect the boiling point of water are the atmospheric pressure and the presence of impurities in the water. As atmospheric pressure increases, the boiling point of water also increases. Impurities in water, such as salt, can raise the boiling point of water due to the change in the composition of the solution.
