Assertion : p- \(\mathrm{O}_2 \mathrm{NC}_6 \mathrm{H}_4 \mathrm{COCH}_3\) is prepared by Friedel Craft's acylation of nitrobenzene. Reason : Nitrobenzene easily undergoes electrophilic substitution reaction.
1 If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion
2 If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion
3 If the Assertion is correct but Reason is incorrect
4 If both the Assertion and Reason are incorrect
5 If the Assertion is incorrect but the Reason is correct.
Explanation:
Nitro benzene does not shows Friedel Craft's acylation reaction because nitro group reactivates the benzene ring towards electrophilic substitution reaction so, it does not undergoes electrophilic substitution reaction. Hence, both assertion and reason is incorrect.

Assertion : Alkyl isocyanides in acidified water give alkyl formamides. Reason : In isocyanides, carbon first acts as a nucleophile and then as an electrophile.
1 If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion
2 If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion
3 If the Assertion is correct but Reason is incorrect
4 If both the Assertion and Reason are incorrect
5 If the Assertion is incorrect but the Reason is correct.
Explanation:
Hence, both assertion and reason is correct and reason correctly explains assertion.
