Current Question (ID: 21350)

Question:

$\text{Given below are two statements:}$ $\text{Statement I:}$ \text{One mole of propyne reacts with excess of sodium to liberate half a mole of } \text{H}_2 \text{ gas.}$ $\text{Statement II:}$ \text{4g of propyne reacts with NaNH}_2 \text{ to liberate NH}_3 \text{ gas which occupies 224 mL at STP.}$ $\text{In the light of the above statements, choose the most appropriate answer from the options given below:}$

Options:

1. $\text{Statement I is correct but Statement II is incorrect.}$
2. $\text{Both Statement I and Statement II are incorrect.}$
3. $\text{Statement I is incorrect but Statement II is correct.}$
4. $\text{Both Statement I and Statement II are correct.}$

Solution:

$\text{CH}_3 - \text{C} \equiv \text{CH} + \text{Na} \rightarrow \text{CH}_3 - \text{C} \equiv \overline{\text{C}} \text{Na}^+ + \frac{1}{2} \text{H}_2 \uparrow$ $\text{CH}_3 - \text{C} \equiv \text{CH} + \text{NaNH}_2 \rightarrow \text{CH}_3\overline{\text{C}} \equiv \overline{\text{C}} \text{Na} + \text{NH}_3$ $\text{Statement I is correct but Statement II is incorrect.}$
