One of the examples of homologous series is given below:
1 answer:
<h3>Answer & Explanation:</h3>
<em><u>Homologous series</u></em><em>:</em><em> </em>Homologous series is the series in which the functional group of any compound and their chemical properties are similar, the difference between any two successive members is same.
<em>Above homologous series is of </em><em>Alkanol</em><em> </em>
<em></em>
Above homologous series is differed by methylene (-CH2-) group. hence the mass diffrence between them would be the mass of -CH2- group.
The compound X is next to CH3CH2OH hence, X will have molecular formula CH3CH2CH2OH which is obtained by addition of a methylene group.
The reason behind the highest boiling point of butanol is his molecular mass, the main reason is the surface area, as the molecular mass increases surface area also increases which lead to increase in the vanderwall forces, due to which boiling point of compound increases. the same compound having least solubility is due to lyophilic/Hydrophobic ( tendency to get dissolved in non aqueous solution) increases & solubility of compound in polar solvents decreases.

Answer : This reaction is an exothermic reaction.
Explanation :
Endothermic reaction : It is defined as the chemical reaction in which the energy is absorbed from the surrounding.
In the endothermic reaction, the energy of reactant are less than the energy of product.
Exothermic reaction : It is defined as the chemical reaction in which the energy is released into the surrounding.
In the exothermic reaction, the energy of reactant are more than the energy of product.
Enthalpy of reaction : It is the difference between the energy of product and the reactant. It is represented as .
The balanced chemical reaction will be:
From the reaction we conclude that the heat energy is released during the reaction that means this reaction is an exothermic reaction.
Hence, the reaction is an exothermic reaction.
