The mechanism of 4-Hydroxybenzaldehyde to compound A has to be shown.

Question

You are trying to decide if there is a single reagent you can add that will make the following synthesis possible without any other major side products: xi 1. ☑ 2. H₂O хе i Draw the missing reagent X you think will make this synthesis work in the drawing area below. If there is no reagent that will make your desired product in good yield or without complications, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. There is no reagent that will make this synthesis work without complications. : ☐ S ☐

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Interpretation Introduction

Interpretation:

The mechanism of 4-Hydroxybenzaldehyde to compound A has to be shown.

(b)

Interpretation Introduction

Interpretation:

The reagent and experiment condition is to be given for the conversion of A to B.

Concept introduction:

Diol is to protect the ketone and aldehyde (carbonyl group). In this reaction acetone is protected as acetal by using ethylene glycol.

(c)

Interpretation Introduction

Interpretation:

The mechanism for the conversion of B to C is to be explained.

Concept introduction:

Wittig Reaction: It is an organic reaction where an aldehyde or a ketone gets converted to epoxide by replacing carbonyl group. A sulfur ylide is used for this conversion. It is a neutral molecule where positively charged sulfur is attached to a negatively charged carbon atom.

(d)

Interpretation Introduction

Interpretation:

The reagent and experiment condition is to be given for the conversion of C to D.

Concept introduction:

Amines reaction with epoxide gives ring opening product.

(e)

Concept introduction:

Diol is to protect the ketone and aldehyde (carbonyl group). In this reaction acetone is protected as acetal by using ethylene glycol.

(f)

Interpretation Introduction

Interpretation:

The possible stereoisomer’s has to be shown if the product is chiral.

Concept introduction:

Chiral:

A molecule is non superimposable on its mirror image is called chiral molecule. Four different atoms attached to a carbon atom is called chiral molecule.

Isomer: A molecule having the same molecular formula but with different chemical structure is called isomer.

Stereoisomers: Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.

Enantiomers: A compound which is non-superimposable mirror image is called enantiomers.

Diastereomers: A compound which is non-superimposable and non-mirror image is called diastereomers.

Racemic mixture: A racemic mixture is simply a mixture containing an equal amount of each enantiomer.

For each reaction below, decide if the first stable organic product that forms in solution will create a new C-C bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution.
