Chapter 16, Problem 16.69P
Interpretation Introduction

Interpretation: The addition of nucleophiles to the carbon-carbon double bond of an α,β unsaturated aldehyde or ketone and the regioselectivity of the addition has to be accounted.

Concept introduction:

Electrophilic addition reaction is an addition reaction where in a chemical bond, a Π bond is Brocken and two new σ bonds are formed, the substrate of an electrophilic addition reaction must have a double bond or triple bond.

Carbocation: The carbon ion that bears a positive charge on it.

Nucleophile: donates pair of electrons to positively charged substrate resulting in the formation of chemical bond.

Electrophile: accepts pair of electrons from negatively charged substrate results in chemical bond formation.

Consider elimination reaction where alkenes are formed when alkyl halides are treated with bases via eliminating one β-proton and one α-halo group of the alkyl halide.

The product of the elimination reaction is depends upon the β-positions of alkyl halide.  If the β-positions are identical and the products formed are also identical.  If the β-positions are different and the products formed are also different.  This means the double bond can form in two different regions so this type of reaction is called regioselective and the products are called as regiochemical outcomes.

CH3 གོན་ནི། ཡོན་ Br₂, H₂C CH₂Br H3C CH3 H₂C CH3 Aldehydes and ketones can be halogenated at their a-position by reaction with Cl₂, Br2, or 12, under acidic conditions. Using Br₂ under acidic conditions, an intermediate enol is formed which adds bromine at the a-position. The reaction stops after the addition of one bromine because the electron-withdrawing halogen decreases the basicity of the carbonyl oxygen, making the protonation less favorable.

Ketones and aldehydes react with sodium acetylide (the sodium salt of acetylene) to give alcohols, as shown in the following example: R1 ОН 1. НС—с: Na* R2 R1 R2 2. Нзо" HC Draw the structure of the major reaction product when the following compound reacts with sodium acetylide, assuming that the reaction takes preferentially from the Si face of the carbonyl group. • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • You do not have to explicitly draw H atoms. • If a group is achiral, do not use wedged or hashed bonds on it.
