Answer 1

Answer:

Resonance is shown by the molecules which have these type of system:-

-Adjacent double bond and positive charge

-Adjacent double bond and negative charge

-Adjacent lone pair and double bond

- Adjacent double bond and free radical

-Two adjacent double bond

-Adjacent lone pair and positive charge.

NH

3

does not have any such kind of system where resonance is possible.

So the correct answer is the option [A]

Answer 2

Answer:

All the other options exhibit resonance whereas Ethylamine doesn't . Therefore, the lone pair of electrons present on the nitrogen atom is localised and available for donation. How satisfied are you with the answer?
