Click to Show Image Description A chemical reaction scheme. On the left is a cyclohexane ring drawn as a flat hexagon. At one ring carbon, a bold wedge bond points downward and to the left, indicating a methyl group (CH₃) projecting toward the viewer. At an adjacent ring carbon, a dashed wedge bond points downward, indicating a bromine (Br) substituent projecting away from the viewer. Above the reaction arrow, the reagent is written as KO with a branched tert-butyl group, representing potassium tert-butoxide. Below the arrow, the solvent DMF is labeled. A single-headed reaction arrow points to the right, indicating the direction of the reaction. No product structure is shown. Click to Show Image Description A chemical reaction scheme. On the left is a cyclohexane ring drawn in a perspective (conformational) representation, showing the ring in a non-flat, angled view. At the uppermost carbon of the ring, two substituents are attached: a methyl group (CH₃) and an iodine atom (I), both on the same carbon. Above the reaction arrow, the reagent methanol (CH₃OH) is written, followed by a comma and the symbol delta (Δ), indicating heat is applied. A single-headed reaction arrow points to the right. No product structure is shown. Enter Figure Caption Here Click to Show Image Description A chemical reaction scheme. The starting material on the left consists of a cyclopentane ring, a five-membered carbon ring drawn in a pentagon shape. Attached to one carbon of the ring is a two-carbon chain. At the end of that chain is a bromine atom (Br), making the full substituent a bromoethyl group on the cyclopentane ring. The bromine is written at the far left of the structure. Above the reaction arrow, the reagent potassium cyanide is written as KC≡N, where the triple bond between carbon and nitrogen is explicitly shown with a triple bond symbol (≡). Below the reaction arrow, the solvent DMSO is labeled. A single-headed reaction arrow points to the right. No product structure is shown. Click to Show Image Description A chemical reaction scheme. The starting material on the left is a cyclohexane ring drawn in a perspective (conformational) representation, showing the ring at an angle. At one carbon of the ring, two methyl groups are attached to the same carbon, forming a gem-dimethyl arrangement, with both methyl groups pointing upward. On the adjacent carbon of the ring, a chlorine atom (Cl) is attached, pointing downward and to the left. Above the reaction arrow, the reagent is drawn as a tert-butyl group with a central carbon bonded to three methyl groups, connected to OK, representing potassium tert-butoxide. Below the reaction arrow, the solvent DMF is labeled. A single-headed reaction arrow points to the right. No product structure is shown. Click to Show Image Description A chemical reaction scheme.

The starting material on the left is a three-carbon chain drawn in a zigzag line structure. The first two carbons are connected by a double bond, represented by two parallel lines, forming a terminal alkene. The third carbon is connected to a bromine atom (Br) by a single bond, positioned at the far right of the chain. The reagent methanol, written as CH₃OH, is labeled below the reaction arrow. A single-headed reaction arrow points to the right. No product structure is shown. Click to Show Image Description A chemical reaction scheme. The starting material on the left is a carbon chain drawn in a zigzag line structure. On the left side of the chain, two carbons form a short ethyl segment. At the next carbon, a bold wedge bond points upward, indicating a methyl group projecting toward the viewer, identifying that carbon as a stereocenter. The chain continues to the right through several methylene groups, terminating in an iodine atom (I) at the far right end. Above the reaction arrow, the reagent potassium hydroxide (KOH) is written. Below the reaction arrow, the solvent is drawn as a two-carbon zigzag line structure with an OH group at the right end, representing ethanol. A single-headed reaction arrow points to the right.

The starting material on the left is drawn as a sawhorse projection, representing a two-carbon chain in a specific conformation. On the front carbon, a methyl group (H₃C) is positioned to the upper left, and a hydrogen (H) is positioned to the lower left. A third hydrogen (H) is shown at the bottom of the front carbon. On the back carbon, a bromine (Br) is positioned at the top, a hydrogen (H) is positioned to the right, and a methyl group (CH₃) is positioned to the lower right. The arrangement of groups on the front and back carbons reflects a specific dihedral relationship in the drawn conformation. Above the reaction arrow, the reagent sodium hydrosulfide (NaSH) is written. Below the reaction arrow, the solvent DMSO is labeled. A single-headed reaction arrow points to the right. No product structure is shown.
