1. What is Acetone?

Acetone, also known as propanone, is a colorless, volatile liquid organic compound with the chemical formula C3H6O. It is the simplest and most important ketone and is widely used as a solvent in various applications. Acetone is miscible with water, ethanol, and ether, making it a versatile solvent for both polar and non-polar substances.

2. The Chemical Structure of Acetone

The molecular structure of acetone consists of a central carbon atom double-bonded to an oxygen atom (the carbonyl group) and single-bonded to two other carbon atoms. This results in a symmetrical structure that can be represented as follows:

2.1 Molecular Formula

The molecular formula of acetone is C3H6O, indicating that it contains three carbon atoms, six hydrogen atoms, and one oxygen atom.

2.2 Structural Formula

The structural formula of acetone can be depicted as:

• H3C - C(=O) - CH3

This representation shows the arrangement of atoms in the molecule, highlighting the carbonyl group (C=O) at the center.

2.3 3D Representation

In three-dimensional space, the acetone molecule adopts a trigonal planar geometry around the carbonyl carbon due to the sp² hybridization of the carbon atom. This geometry is essential for understanding the interactions of acetone with other molecules.
