Answer: The boiling point will be highest for butan-1-amine.
Explanation:
Dipole moment is defined as the separation of positive and negative charges.
More the dipole moment of a compound, more separation between the positive and negative charges and more polar will be the bond.
When a compound has strong dipole-dipole interactions and is heated, more energy will be required to overcome these strong interactions and hence, will have high boiling point. This means that polar molecules have high boiling points than non-polar molecules.
In the given question:
The dipole moment is highest for butan-1-amine which is 3.2 D and will also have highest boiling point among the given molecules.
Hence, the correct answer is butan-1-amine.
Answer:
Moles = Molecules / (6.0221415 x 10^23)
Explanation:
Answer:
This is a physical change because it's not permanent and no chemical reaction occurs. Mixtures - Mixing together materials where one is not soluble in the other is a physical change. Note the properties of a mixture may be different from its components.
Explanation:
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.
In a physical change, the molecules are rearranged while their actual composition remains same. In a chemical change, the molecular composition of a substance completely changes and a new substance is formed. Some example of physical change are freezing of water, melting of wax, boiling of water....
The pan would heat faster because in order for the water to get hot the pan needs to be hot as well.
