Current Question (ID: 17901)

Question:

$\text{Select the correct option based on statements below:}$ $\text{Assertion (A):}$ \text{The stability of a crystal is reflected by the magnitude of its melting point.}$ $\text{Reason (R):}$ \text{Greater the intermolecular forces of attraction, the higher will be the stability and melting point of the substance.}$

Options:

1. $\text{Both (A) and (R) are true and (R) is the correct explanation of (A).}$
2. $\text{Both (A) and (R) are true but (R) is not the correct explanation of (A).}$
3. $\text{(A) is true but (R) is false.}$
4. $\text{Both (A) and (R) are false.}$

Solution:

$\text{Stability} \propto \text{Melting point}$ $\text{The higher the melting point, the greater is the intermolecular force of attraction, i.e., more will be the stability of the substance as compared to a substance having low melting point.}$ $\text{Example: Melting point of Ethyl alcohol = 158.8 \text{ K} \text{ and methane = 89.34 \text{ K}.}$ $\text{So, the stability of ethyl alcohol is more than methane as the force of attraction is stronger in ethyl alcohol.}$
