Please answer these Assertion Reason
Solution 17: The melting point and boiling point of ethanol are indeed lower than that of sodium chloride. This is because ethanol is a covalent compound, while sodium chloride is an ionic compound. The melting and boiling points of covalent compounds are generally quite low compared to those of ionic compounds. This is because the melting of ionic compounds involves breaking ionic bonds whereas the melting of covalent compounds involves disrupting the weak forces between molecules.
Hence, both assertion and reason are true and reason is the correct explanation of the assertion.
Solution 19: The process of adding water to an acid is highly exothermic, therefore it is always recommended that acid should be added to water. If it is done the other way, then it might be possible that because of the large amount of heat generated, the mixture may splash out and cause burns.
Hence, assertion is false but reason is true.
