OCH 3 group shows +M, thus destabilise carbanion, while - NO 2 group shows, -M and decreases electron density on carbanion and make it more stable. Thus stability order is: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/842495ee91c9eab87302d18b61c411bc-.png" />

Q. Consider the following carbanions :

Correct order of stability is

$I > II > III$

$III > II > I$

$II > III > I$

$I > III > II$

$OC H_{3}$ group shows $+ M$ , thus destabilise carbanion, while $- N O_{2}$ group shows, $- M$ and decreases electron density on carbanion and make it more stable. Thus stability order is :

Q. Consider the following carbanions : Correct order of stability is

I>II>III

III>II>I

II>III>I

I>III>II
