Question

Question: Classify each OH group and halogen in dexamethasone, a synthetic steroid, as ${\mathbf{1}}^{\mathbf{0}}$, ${\mathbf{2}}^{\mathbf{0}}$or ${\mathbf{3}}^{\mathbf{0}}$ .

Short answer

Answer

Step-by-step solution

Classification of alcohol group in a compound

• Primary alcohol: If the hydroxyl group is attached with $1^0$carbon.
• Secondary alcohol: If the hydroxyl group is attached with $2^0$carbon.
• Tertiary alcohol: If the hydroxyl group is attached with $3^0$carbon.

Halogen

The halogens are represented by F, Cl, Br, I atoms.

• Primary halogen: If the given group is bonded with$1^0$carbon.
• Secondary halogen: If the given group is bonded with $2^0$ carbon.
• Tertiary halogen: If the given group is bonded with $3^0$ carbon.

Information on dexamethasone

The $1^0$, $2^0$ and $3^0$ classification on dexamethasone are represented as:
