(a)
Interpretation:
Configuration for the chirality center should be identified.
Concept introduction:
Chiral: Four different atoms attached to a carbon atom is called chiral molecule.
Stereoisomers: Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.
Cahn–Ingold–Prelog system: The first priority goes to the atom in a molecule whose
Draw a curve from the first-priority substituent through the second-priority substituent and then through the third.
If the curve goes clockwise, the chiral center is designated R; if the curve goes counterclockwise, the chiral center is designated S.
To find: Configuration for the chirality center

Stereoisomers: Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.
Cahn–Ingold–Prelog system: The first priority goes to the atom in a molecule whose atomic number is higher. After assigning the priorities to each of the substituents, rotate the molecule so that the number-four priority substituent is oriented in the back.
Draw a curve from the first-priority substituent through the second-priority substituent and then through the third.
If the curve goes clockwise, the chiral center is designated R; if the curve goes counterclockwise, the chiral center is designated S.

- टे Predict the major products of this organic reaction. Be sure to use wedge and dash bonds when necessary, for example to distinguish between different major products. ☐ ☐ : ☐ + NaOH HO 2 Click and drag to start drawing a structure.arrow_forwardShown 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.
