Interpretation Introduction

(a)

Interpretation:

The structure of the product is to be drawn for the given reaction from the given data.

Concept introduction:

The α,β- unsaturated carbonyl compounds have two electrophilic centers. One is the carbonyl carbon yielding the direct addition product; the second is the β carbon yielding the conjugate addition product.

Thus, both can react with the nucleophile depending, on the nature of the nucleophile and the regioselectivity of the reaction.

When the nucleophile adds to the carbonyl carbon, the reaction yields a 1, 2-addtion product, and the final product is alcohol in this case.

When the nucleophile adds to the β carbon of the carbonyl compound, the reaction yields a 1, 4-addition product, keeping the carbonyl group intact.

A broad absorption between 3200 - 3600 cm-1 in IR spectrum is characteristic of an O-H stretching, and a band near 1700 cm-1 is characteristic of the carbonyl group.

Interpretation Introduction

(b)

Interpretation:

it is to be argued whether the nucleophile adds reversibly or irreversibly to the carbonyl group in the given reaction.

How many milliliters of 97.5(±0.5) wt% H2SO4 with a density of 1.84(±0.01) g/mL will you need to prepare 2.000 L of 0.110 M H2SO4? If the uncertainty in delivering H2SO4 is ±0.01 mL, calculate the absolute uncertainty in the molarity (0.110 M). Assume there is negligible uncertainty in the formula mass of H2SO4 and in the final volume (2.000 L) and assume random error.
Don't used hand raiting and don't used Ai solution
What should be use to complete the reaction? CN CN
