An increase in the temperature of a solution usually: a)increases the boiling point. b)increases the solubility of a gas in the
1 answer:
Answer: Option (c) is the correct answer.
Explanation:
Relation between kinetic energy and temperature is as follows.
Since, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then this will also lead to increase in kinetic energy of the molecules of a substance.
So, when a solid substance is dissolved in a solution whose temperature is increased then molecules of the solid will also gain kinetic energy. As a result, more number of collisions will occur due to which bond between the molecules of solid will break.
Therefore, there will be increase in solubility of the solid.
Thus, we can conclude that an increase in the temperature of a solution usually increases the solubility of a solid solute in the solution.

Here we have to explain and predict the product of the reaction between hept-3-yne and bromine (Br₂)
The reaction between hept-3-yne and bromine produces <em>trans</em>-3,4-dibromo-3-heptene.
The reaction between the unsaturated hydrocarbon with halogen remove the unsaturation in the molecule and produces di halo compound. The reaction proceed through the formation of bromonium ion.
In this reaction as the unsaturation present in the middle of the alkyl chain i.e. hept-3-yne. The reaction will stop after the formation of di-halo compound with one double bond as shown in the figure.
The product will be exclusively trans product as the bromine is a bulky group and the formation of bromonium ion (intermediate) will be one side of the unsaturated compound.
