Question

Assertion: Pure $CHC{l}_3$ does not give precipitate with $AgN{O}_3$ solution.
Reason: $CHC{l}_3$ is covalent compound.

• A. Both Assertion and Reason are true and Reason is the correct explanation to Assertion
• B. Both Assertion and Reason are true and Reason is not the correct explanation to Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true

Answer 1

The correct option is A Both Assertion and Reason are true and Reason is the correct explanation to Assertion

White ppt. will be obtained when $AgCl$ forms in solution but as pure $CHC{l}_3$ is covalent compound so it doesn't provide chloride ion to react with $AgN{O}_3$ and white ppt will not form.
But impure chloroform contains $HCl$, which reacts with $AgN{O}_3$ and white ppt of $AgCl$ forms due to reaction given above.
