Organic Basics (GOC) · Carbanion stability substituent effects

Arrange the following carbanions in the decreasing order of stability

(I) $p$ –Br– $\ce{C6H4}$ – $\overset{\ominus}{\ddot{\mathrm{C}}}\mathrm{H_2}$
(II) $\ce{C6H5}$ – $\overset{\ominus}{\ddot{\mathrm{C}}}\mathrm{H_2}$
(III) $p$ – $\ce{CH3O}$ – $\ce{C6H4}$ – $\overset{\ominus}{\ddot{\mathrm{C}}}\mathrm{H_2}$
(IV) $p$ –CHO– $\ce{C6H4}$ – $\overset{\ominus}{\ddot{\mathrm{C}}}\mathrm{H_2}$
(V) $p$ – $\ce{CH3}$ – $\ce{C6H4}$ – $\overset{\ominus}{\ddot{\mathrm{C}}}\mathrm{H_2}$
