Question

Which is more stable between nitroethane and ethoxide?

Answer 1

Here is your asnwer:

Nitroethane is a very weak acid and the position of equilibrium lies well to the left. nitroethane can lose a hydrogen ion because the ethoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring. The more stable the ion the more stable the compound is.
