### Reaction Pathways and Stereochemistry

This section illustrates two reaction pathways, showcasing the importance of stereochemistry in organic reactions.

#### Schematic Representation of Reaction 1:

The first reaction begins with a carbon center (denoted with an asterisk) attached to:
- A hydroxyl group (OH)
- A deuterium atom (D)
- An ethyl group (CH3CH2)
- A variable group (R)

This structure is converted to a new molecule where the carbon center is now bonded to a nitrile group (C≡N). The stereochemistry around the carbon center is retained.

#### Schematic Representation of Reaction 2:

The second reaction features a similar starting molecule with an almost identical configuration:
- Hydroxyl group (OH)
- Deuterium atom (D)
- Ethyl group (CH3CH2)
- Variable group (R)

In this case, the product after the reaction is a molecule where the carbon center (with retained stereochemistry) is bonded to an isothiocyanate group (C=S).

**Key Points**
* The diagrams show the specific 3D orientation of the bonds (dashed and wedged lines) to indicate the stereochemistry of the elements around the central carbon.
* The consistent use of "try" suggests this is an educational exercise, hinting that the task involves solving or predicting reaction products or pathways.
* The variable group (R) remains consistent in both reactants and products, indicating its preservation throughout the reactions.

#### Explanation of Symbols:
- **Hydrogen (H)**: A simple hydrogen atom.
- **Deuterium (D)**: An isotope of hydrogen denoted by "D".
- **Ethyl Group (CH3CH2)**: A common alkyl substituent.
- **R Group**: Represents a variable substituent which may differ depending on the specific molecule under consideration.
- **Nitrile Group (C≡N)**: A functional group containing a carbon triple-bonded to a nitrogen.
- **Isothiocyanate Group (C=S)**: A functional group featuring a carbon double-bonded to sulfur and nitrogen.

#### Diagram Interpretation:
- Bold, solid lines: Bonds lying in the plane of the paper.
- Dashed lines: Bonds extending behind the plane of the paper.
- Wedged lines: Bonds projected out of the plane of the paper.

These representations are crucial for understanding how the spatial arrangement of atoms influences
