Chemistry Question on Organic Chemistry- Some Basic Principles and Techniques

Identify the functional group that has electron donating inductive effect

A

\ce−COOH\ce{ - COOH}

B

\ce−CN\ce{-CN}

C

\ce−CH3\ce{-CH_3}

D

\ce−NO2\ce{-NO_2}

Answer

\ce−CH3\ce{-CH_3}

Explanation

Solution

The functional group that has electron donating or positive inductive effect is ?CH3? CH _{3} Since, the positive inductive effect is due to the presence of an electron donating groups within the polar bond. Thus, option (c) is correct as rest of the three groups (?COOH,?CN,?NO2)\left(?COOH ,?CN ,? NO _{2}\right) are electron withdrawing in nature.
