what are the common types of resonance structures in organic chemistry. please provide an illustration for these types
1) Draw two resonance structures for nitrobenzene depicting the deactivation of the benzene ring. Include any formal charges in your drawing. 2) In step 17, methanol dissolved the starting material but not the product. Explain why the presence of a nitro group makes a compound less soluble in organic solvents.
1) Draw structures for compounds named below. A) (2)-1-bromo-2-chloro-1-heptene B) 4-chloro-4-fluoro-2-octyne 2) Give IUPAC name for the following structure. 3) For each reaction below, indicate which starting material is the Nucleophile and which is the Electrophile. Show arrows to demonstrate how the transformation occurs. →^_^tts a Porto ~ onde gi 4) Draw a mechanism for the conversion of the shown starting material to the corresponding product. 5) In the transformation below, a starting material is treated with HCl to form...

Please help!!
1. a. Draw the structures of A and B (resonance structures), and C (tetrahedral intermediate). Use curved arrows to show how each structure is formed b. Draw the structure of the Nu: you would use to make CompoundD O (tetrahedral intermediate) он c. (i) Explain why H does not react with a pi bond in the ring in Compound Z. (ii) Which resonance structure, A or B, shows why reacting H with the ketone makes the more reactive?...
