4. Explain why aliphatic amines are much less stable than those that have at least one aromatic group attached to the carbon-nitrogen double bond. 5. Write the structure(s) of the products you would expect to get if you react N- cinnamaldehyde-m-nitroaniline with catalytic hydrogenation (that means adding H2 and Pt or Pd).

Explain this resonance and basicity problem? Why does the Guanidine top nitrogen have a negative dipole?...
Explain this resonance and basicity problem? Why does the
Guanidine top nitrogen have a negative dipole? Doesn't the
resonance hybrid cause the bond to be less than 1 full bond so it
causes it to be a positive dipole? Also doesn't the resonance in
guanidine cause it to be a weaker base than ammonia?
17. (5) Let's decide which is the stronger base ammonia or guanidine. Circle one answer each in H2N parts (a) (c) below. Guanidine (a) What is...
