Current Question (ID: 7442)

Question:

$\begin{array}{|l|l|}\hline\text{Assertion (A):} & \text{The number of molecules in 2 moles of NH}_3\text{ is equal to the}\\& \text{number of molecules in 4 moles of CH}_4.\\\hline\text{Reason (R):} & \text{Both are chemically similar species.}\\\hline\end{array}$

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:

$\text{Hint: 1 mol} = 6.022 \times 10^{23} \text{ molecule}$ $\text{2 moles of NH}_3 \text{ contain } 2 \times 6.022 \times 10^{23} \text{ molecules of NH}_3.$ $\text{4 moles of CH}_4 \text{ contain } 4 \times 6.022 \times 10^{23} \text{ molecules of CH}_4$ $\text{Thus, the number of molecules of CH}_4 \text{ is more than NH}_3.$ $\text{Both are chemically similar species is not a true statement. Ammonia and}$ $\text{methane are two different compounds hence the physical and chemical}$ $\text{properties of these two molecules are different.}$ $\text{Hence, Both Assertion and Reason are false statements.}$
