Art-Labelling Activity: Nail Structure 13 of 30 Drag the appropriate labels to their respective targets.
Draw 3-fluoro-2-methylpropan-1-amine
The Correct Answer and Explanation is :
Here are the responses to the two tasks:
Task 1: Nail Structure
For labeling the nail structure, refer to the anatomy diagram in the provided image:
- Nail Plate: The visible hard part of the nail.
- Lunula: The crescent-shaped white area at the base of the nail plate.
- Cuticle (Eponychium): The thin strip of tissue at the base of the nail plate that protects the nail matrix.
- Nail Matrix: The tissue under the base of the nail plate responsible for nail growth.
- Nail Bed: The skin beneath the nail plate.
- Hyponychium: The skin located under the free edge of the nail plate.
Each part of the nail serves a specific function, primarily protection, and contributes to nail growth.
Task 2: Drawing 3-Fluoro-2-Methylpropan-1-Amine
The correct structure for 3-Fluoro-2-Methylpropan-1-Amine is as follows:
- The parent chain is propane (3 carbon atoms).
- Substituents:
- Fluoro group (-F) is attached to carbon 3.
- Methyl group (-CH₃) is attached to carbon 2.
- Amino group (-NH₂) is attached to carbon 1.

HExplanation (300 Words)
1. Nail Structure: Nails protect the tips of fingers and toes, providing strength and precision during various activities. The nail plate, composed of keratin, forms the visible part, while the underlying nail matrix generates new cells. The lunula, often a pale semicircular area, marks the end of the matrix. The cuticle seals the area between the skin and nail to prevent infection. The nail bed supports the nail plate, aiding in its adhesion. The hyponychium acts as a barrier beneath the nail plate’s free edge. Proper care of these structures prevents disorders like onychomycosis (fungal infection).
2. Chemical Structure: In organic chemistry, the International Union of Pure and Applied Chemistry (IUPAC) naming system allows systematic identification of molecules. Here, the base structure is propane. The substituents are numbered to give the lowest locants. Fluoro at carbon 3 and methyl at carbon 2 indicate their positions. The amino group at carbon 1 ends the name as “-amine.” Fluoro groups influence reactivity by withdrawing electrons, while the amine group contributes nucleophilicity. This molecule could have pharmaceutical relevance due to the amine group’s biological interactions.
