Molecular Structure
CH3COH CH2CH3 is an organic compound with the molecular formula C4H8O. It is a colorless liquid with a characteristic odor. The molecular structure of CH3COH CH2CH3 can be described as follows:
The molecule consists of a central carbon atom bonded to two methyl groups (CH3) and two hydrogen atoms. The carbon atom is also bonded to an oxygen atom, which is in turn bonded to a hydrogen atom. The molecule has a tetrahedral shape, with the carbon atom at the center and the four other atoms at the corners.
Bonding
The bonds between the atoms in CH3COH CH2CH3 are covalent bonds. A covalent bond is formed when two atoms share one or more pairs of electrons. In CH3COH CH2CH3, the carbon-carbon bonds are formed by the sharing of two pairs of electrons, and the carbon-hydrogen bonds are formed by the sharing of one pair of electrons.
The carbon-oxygen bond is formed by the sharing of two pairs of electrons, and the oxygen-hydrogen bond is formed by the sharing of one pair of electrons.
Arrangement of Atoms
The atoms in CH3COH CH2CH3 are arranged in a tetrahedral shape. This means that the four atoms that are bonded to the central carbon atom are arranged in a three-dimensional space in such a way that they are as far apart from each other as possible.
The tetrahedral shape is the most stable arrangement for these atoms because it minimizes the repulsion between the electrons in the bonds.

Physical Properties: Line Structure For Ch3coh Ch2ch3 2
CH3COH CH2CH3 2, commonly known as ethyl acetate, exhibits distinct physical properties that are influenced by its molecular structure. These properties play a crucial role in its various applications.
The following table summarizes the key physical properties of ethyl acetate:
| Property | Value |
|---|---|
| Melting point | -83.6 °C |
| Boiling point | 77.1 °C |
| Density | 0.902 g/cm3 |
| Solubility | Miscible with water and organic solvents |
Melting Point and Boiling Point
The melting point of ethyl acetate is -83.6 °C, and its boiling point is 77.1 °C. These values indicate that ethyl acetate is a liquid at room temperature. The intermolecular forces between ethyl acetate molecules are relatively weak, allowing them to flow easily at room temperature.
However, upon cooling, these forces become stronger, causing the molecules to pack together more tightly and form a solid.
Density
Ethyl acetate has a density of 0.902 g/cm 3, which is slightly lower than that of water. This low density is due to the presence of the bulky ethyl group, which makes the molecules less dense than water molecules.
Solubility
Ethyl acetate is miscible with both water and organic solvents. This property is attributed to its polar and nonpolar regions. The polar carbonyl group allows it to interact with water molecules, while the nonpolar ethyl group enables it to dissolve in organic solvents.
Chemical Properties
CH3COH CH2CH3 2, also known as ethyl acetate, possesses distinctive chemical properties that stem from its molecular structure. These properties include reactivity, flammability, and toxicity, all of which play a crucial role in its applications and handling.
Reactivity
Ethyl acetate is a relatively reactive compound due to the presence of the ester functional group (-COOCH2CH3). This group undergoes various reactions, including hydrolysis, saponification, and transesterification. Hydrolysis, for instance, involves the reaction of ethyl acetate with water to form acetic acid and ethanol.
Flammability
Ethyl acetate is highly flammable due to its low flash point (-4 °C or 24.8 °F). This property arises from the presence of the hydrocarbon chain (CH2CH3) attached to the ester group. The flammable nature of ethyl acetate necessitates proper storage and handling to prevent fire hazards.
Toxicity
Ethyl acetate exhibits moderate toxicity. Inhalation of its vapors can cause irritation of the respiratory tract, while skin contact can lead to dermatitis. Ingestion of large amounts can result in nausea, vomiting, and abdominal pain. It is essential to handle ethyl acetate with appropriate safety measures, such as using proper ventilation and protective gear.
