1.	Which is expected to be more stable, O_2 NCH_2CH_2O or CH_3CH_2O and why?
Answer» Answer :`O_2N-CH_2-CH_2-O^-` is more STABLE because `-NO_2` group being ELECTRON withdrawing (-I) disperses the NEGATIVE charge on oxygen ATOM. In the other +1 effect of ALKYL group intensifies the negative charge (unstable).
