Concept explainers
(a)
Interpretation: The chair form of trans-and cis-decalin for the cyclohexane rings are to be drawn.
Concept introduction: The different spatial arrangements of atoms that results from the rotation about single bonds are called conformational isomers. The chair conformation of cyclohexane consists of six axial and six equatorial bonds.
The six axial bonds present one on each carbon atom, are parallel and alternate to each other and are in up-down position.
The six equatorial bonds present one on each carbon atom, are present in three sets of two parallel ring bonds. They are in alternate position between the sides around the ring.
(b)
Interpretation: An explanation corresponding to the fact that the trans isomer is more stable is to be stated.
Concept introduction: The different spatial arrangements of atoms that results from the rotation about single bonds are called conformational isomers. When two substituents in a conformation are in up or down direction then it is known as cis conformation. But if one substituent is in upward direction and the other is facing down direction, then the conformation is known as trans.

- 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. NH2 tu ? ? OH Will the first product that forms in this reaction create a new CC bond? Yes No Will the first product that forms in this reaction create a new CC bond? Yes No C $ ©arrow_forwardAs the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C-C bond as its major product: 1. MgCl ? 2. H₂O* If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. This reaction will not make a product with a new CC bond. G marrow_forwardIncluding activity coefficients, find [Hg22+] in saturated Hg2Br2 in 0.00100 M NH4 Ksp Hg2Br2 = 5.6×10-23.arrow_forward
