Assertion Rectified spirit can be further purified by adding a dehydrating agent
Assertion Rectified spirit can be further purified by adding a dehydrating agent. Reason Addition of \( H_{2} S O_{4} \) to \( 96 \% \) ethyl alcohol gives \( 100 \% \) ethyl alcohol
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Both Assertion and Reason are incorrect
Step-by-step solution
Rectified spirit (95% ethanol) can be further purified by adding a dehydrating agent like calcium oxide to remove water, so the assertion is correct. However, adding H2SO4 to ethanol does not yield 100% ethanol; instead, it causes dehydration to ethylene and other reactions, making the reason incorrect.
