What is the major difference between the two-dimensional and three- dimensional models of ethane and methane? When might you choose to use a two-dimensional model rather than a three-dimensional model when representing one of the molecules?
You guys are no help
3D - more specific and harder to draw, 2D - much easier and provides more details.
I sort of dragged it out for you :)
The major difference is that the two-dimensional model doesn't show the C-H angles. For example, three-dimensional models are needed to show stereo-isomerism

FIRST: well uh...the two dimensional model of the methane shows the carbon atom bonded to 4 hydro. atoms and i think the ethane one shows its bound by only 2
SECOND: and i believe they differ because methane is tetrahedal and ethane is trigonal pyramidal
your welcome because everyone else is an IDIOT 🥺❤
The major difference between the two-dimensional (2D) and three-dimensional (3D) models of ethane and methane lies in the way the molecules are represented in space.
In a 2D model, the molecules are represented on a flat plane, usually using a structural formula or skeletal formula. The 2D model shows the connectivity between the atoms and the arrangement of the bonds, but it does not provide any information about the actual spatial orientation of the atoms in three-dimensional space.
On the other hand, a 3D model represents the molecules in three dimensions, providing information about the spatial arrangement of the atoms. It includes the bond angles, bond lengths, and the overall geometry of the molecule, which can have important implications for its chemical properties.
When it comes to choosing between a 2D and a 3D model, it primarily depends on the purpose and level of detail needed. A 2D model is useful when you want to focus solely on the connectivity and structure of atoms in a molecule. It is a simpler representation that allows you to easily depict and understand the molecular formula, functional groups, and chemical bonding.
A 2D model is often used in organic chemistry when drawing reaction mechanisms, analyzing molecular structures, or representing chemical reactions on paper or in textbooks. It is also commonly used to represent molecules in computer software or databases.
On the other hand, a 3D model is necessary when you want to understand the true spatial arrangement of the atoms in a molecule. It is particularly important when studying molecular properties related to shape, chirality (handedness), intermolecular interactions, and stereochemistry. Researchers in fields like medicinal chemistry, computational chemistry, and materials science often rely on 3D models to better understand molecular behavior and to predict how molecules interact with each other.
In summary, the choice between a 2D and a 3D model depends on the specific context and level of detail required. A 2D model is sufficient for understanding the connectivity and basic structure, while a 3D model is needed for a more detailed analysis of spatial arrangement and properties.
