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).

Reaction 1: Nitration HNO3 NO2 H2SO4, H20 NO2 toluene NO2 ortho meta para Procedure for Reaction 1: 1) To a stirred solution of 3 mL (44.7 mmoles) 67 % HNO3 in 3.75 mL of water, H2SO4 (9 mL) was slowly added at 10-15 °C. 2) This nitrating solution was added dropwise with vigorous stirring to 4 mL (37.5 mmoles) of toluene while cooling in ice-water in order to maintain the reaction temperature between 15 and 25 °C. 3) Stirring was...

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...
