Nitroethoxide ion (O2NCH2CH2O–) is more stable than ethoxide ion (CH3CH2O–) due to -I effect of nitro group which decreases the negative charge of oxide ion of nitroethoxide ion leading to stability. In contrast, CH3CH2 has +I-effect. It, therefore, tends to intensify the -ve charge and hence destabilizes it.
