The Wolff–Kishner reaction uses hydrazine (H2NNH2) and hydroxide (–OH) to reduce a carbonyl to the alkane. The first steps of the mechanism convert a carbonyl to a hydrazone in a manner similar to imine formation. Draw the mechanism arrows for the reaction from the hydrazone to the alkane. Be sure to add lone pairs of electrons and nonzero formal charges to all species.
Please help me with the last two steps. I keep getting them marked wrong. Please and thank you!
Br Brz CH3 CH3 H3C CH2CI2 H3C Br Electrophilic addition of bromine, Br2; to alkenes yields a 1,2-dibromoalkane. The reaction proceeds through a cyclic intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH,Cl). In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion to yield the product. Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ion so that a product with anti stereochemistry is formed. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions Br: :Br: .CH3 H3C H3C CH3 Br:

In this reaction with bromine, monosubstitution of lakane A forms a mixture of organic product. Show the structures of two monosubstituted organic products that are formed.
Nucleophilic aromatic substitution involves the formation of a resonance-stabilized carbanion intermediate called a Meisenheimer complex as the nucleophile attacks the ring carbon carrying the eventual leaving group; electron-withdrawing groups ortho and/or para to the site of attack help to stabilize this structure via resonance. For the reaction below, draw the structure of the stabilized reaction intermediate in the box below. CI F3C CF3 NO₂ F3C N CF3 NO₂ • You do not have to consider stereochemistry. • Draw the Meisenheimer complex with a formal charge of 0 on the nucleophilic atom. If more than one resonance structure is possible, only draw the most important one.
