Draw a structural formula for the major organic anion formed when 2- ethylbutanal is reacted with Tollens' reagent. You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • If no reaction occurs, draw the organic starting material. P. opy aste CH4 ChemDoodle Previous Nex

Suppose you were told that each reaction  is a substitution reaction, but you were not told the mechanism. Describe how you could conclude from the structure of the haloalkane or cycloalkene, the nucleophile, and the solvent that each reaction is an SN1 reaction.

Addition of HBr to 1-phenylpropene yields only (1- bromopropyl) benzene. Propose a mechanism for the reaction, and explain why none of the other regioisomer is produced.

Is the structure, transition state and relative stereochemistry of the products is correct?  Is the curly arrow mechanism is correct ?

When 1 mole of buta-1,3-diene reacts with 1 mole of HBr, both 3-bromobut-1-ene and 1-bromobut-2-ene are formed. Propose a mechanism to account for this mixture of products.
