Current Question (ID: 10640)

Question:

$\text{Select the correct option based on statements below:}$ $\textbf{Assertion (A):} \text{SF}_6 \text{ cannot be hydrolysed but SF}_4 \text{ can be.}$ $\textbf{Reason (R):} \text{Six F-atoms in SF}_6 \text{ prevent the attack of H}_2\text{O on sulphur atom of SF}_6$

Options:

1. $\text{Both (A) and (R) are True and (R) is the correct explanation of (A).}$ (Correct)
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. $\text{(A) is False but (R) is True.}$

Solution:

$\textbf{HINT:} \text{Steric hindrance in the case of SF}_6$$ $\textbf{Explanation:}$$ $\textbf{STEP 1:} \text{SF}_4 \text{ is see-saw in shape while SF}_6 \text{ is octahedral in shape.}$$ $\textbf{STEP 2:}$$ $\text{SF}_6 \text{ is not easily hydrolysis because here S atom is surrounded by 6F atom}$$ $\text{so it's complected for H}_2\text{O} \text{ to attack SF}_6 \text{ but in}$$ $\text{case of SF}_4 \text{ here S atom is surrounded by 4F atom so it's to attack by H}_2\text{O.}$$ $\text{Hence, Assertion and reason both are True and the reason is the correct}$$ $\text{explanation of assertion.}$
