The reason should be explained for the given compound has four stereoisomers when it has only one asymmetric center. Concept introduction: The total number of stereoisomers can be calculated by using following formula, The total number of stereoisomers = 2 n n = number of chiral carbon Cis – trans isomerism (or) geometric isomerism or configurational isomerism: The two similar groups (or higher priority groups) are in same side in double bond of alkenes is called as cis isomer (or Z -isomer). Two similar groups (or higher priority groups) are opposite side in double bond of alkenes is called as trans isomer (or E -isomer). Example:

Interpretation Introduction

Interpretation:

The reason should be explained for the given compound has four stereoisomers when it has only one asymmetric center.

Concept introduction:

The total number of stereoisomers can be calculated by using following formula,

The total number of stereoisomers = 2nn = number of chiral carbon

Cis–trans isomerism (or) geometric isomerism or configurational isomerism:

The two similar groups (or higher priority groups) are in same side in double bond of alkenes is called as cis isomer (or Z-isomer). Two similar groups (or higher priority groups) are opposite side in double bond of alkenes is called as trans isomer (or E-isomer).

A student proposes the following two-step synthesis of an ether from an alcohol A: 1. strong base A 2. R Is the student's proposed synthesis likely to work? If you said the proposed synthesis would work, enter the chemical formula or common abbreviation for an appropriate strong base to use in Step 1: If you said the synthesis would work, draw the structure of an alcohol A, and the structure of the additional reagent R needed in Step 2, in the drawing area below. If there's more than one reasonable choice for a good reaction yield, you can draw any of them. ☐ Click and drag to start drawing a structure. Yes No ロ→ロ 0|0 G Х D : ☐ ப

Shown below are five NMR spectra for five different C6H10O2 compounds. For each spectrum, draw the structure of the compound, and assign the spectrum by labeling H's in your structure (or in a second drawing of the structure) with the chemical shifts of the corresponding signals (which can be estimated to nearest 0.1 ppm). IR information is also provided. As a reminder, a peak near 1700 cm-1 is consistent with the presence of a carbonyl (C=O), and a peak near 3300 cm-1 is consistent with the presence of an O–H. Extra information: For C6H10O2 , there must be either 2 double bonds, or 1 triple bond, or two rings to account for the unsaturation. There is no two rings for this problem. A strong band was observed in the IR at 1717 cm-1
