CHXI12:ORGANIC CHEMISTRY SOME BASIC PRINCIPLES AND TECHNIQUES

317744 Assertion :
\(\mathrm{NC}-\mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{COOH}\) is called 3 cyanopropanoic acid while \(\mathrm{OHC}-\mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{COOH}\) is called 4-oxobutanoic acid.
Reason :
While naming polyfunctional compounds, \(-\mathrm{COOH}\) group gets preference over cyano and oxo groups.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
