Substitution Reactions Predicting the product of a nucleophilic substitution reaction Draw the organic product you would expect to isolate from the nucleophilic substitution reaction between the molecules shown. Note: You do not need to draw any of the side products of the reaction, only the substitution product. HO + + Br xx X S C Click and drag to start drawing a structure.

Write the products of the following aromatic electrophilic substitutions

Following is a balanced equation for the allylic bromination of propene. CH2==CHCH3 + Br2 h CH2==CHCH2Br + HBr (a) Calculate the heat of reaction, H 0, for this conversion. (b) Propose a pair of chain propagation steps and show that they add up to the observed stoichiometry. (c) Calculate the H 0 for each chain propagation step and show that they add up to the observed H 0 for the overall reaction.

Can you explain it? Provide examples with the various steps and explanations. How halogens affect the boiling/melting point? Does number of halogens affect it? For example, Ch3-Ch3 vs Ch3-Br vs Br-Ch3-Br

The reaction shown proceeds via a single transition state with a trigonal bipyramidal geometry. C1 C2 Br: + H3C 0: Two curved arrows are required to indicate all of the bond-making and bond-breaking processes in this reaction. Where should one of the arrows be drawn, if CH3O is the nucleophile? from a Br LP to the O atom from C1 to the O atom from C2 to the O atom from the C-O bond to Br from an O LP to C1 from an O LP to C2

2. Provide an arrow pushing mechanism for the following reaction. Show all intermediate structures and formal charges. You do not need to show resonance structures

N,N-diethyl-m-toluamide (DEET) is the active ingredient in many insect repellent preparations. Following is one of the steps in its synthesis. In the box below draw the structure of the product of this reaction. MgBr H3C 0 ▾ + 1. CO₂ 2. H3O+ • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading. • Draw the Grignard reagent as a covalent magnesium bromide. n [ ]# product ChemDoodleⓇ 28
