Current Question (ID: 10959)

Question:

$\text{Assertion (A): CCl}_4 \text{ doesn't give precipitate of AgCl on heating with } \text{AgNO}_3.$ $\text{Reason (R): CCl}_4 \text{ is a non-polar molecule.}$

Options:

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

Solution:

$\text{Hint: Covalent molecule will not give ppt of AgCl with } \text{AgNO}_3.$ $\text{Explanation: CCl}_4 \text{ will not give the white precipitate of AgCl on heating it with silver nitrate. This is because the chlorine atoms are covalently bonded to carbon in CCl}_4.$ $\text{To obtain the precipitate, it should be present in ionic form and for this, it is necessary to prepare the Lassaigne's extract of CCl}_4.$
