As a chemistry expert with a keen interest in molecular geometry, I'm delighted to delve into the structure of acetylene, with the chemical formula C2H2. This molecule is a fundamental building block in organic chemistry and is known for its unique properties, which are largely influenced by its molecular geometry.
Acetylene, C2H2, is a simple hydrocarbon molecule that is composed of two carbon atoms and two hydrogen atoms. To understand the geometry of C2H2, we must consider the Valence Shell Electron Pair Repulsion (VSEPR) Theory. This theory states that the electron pairs in the valence shell of an atom will repel each other and arrange themselves in a way that minimizes this repulsion. The VSEPR model is a powerful tool for predicting the three-dimensional shape of molecules.
In the case of acetylene, each carbon atom is sp hybridized. This means that one of the 2s electrons is promoted to the 2p orbital, resulting in two hybrid orbitals and two unhybridized p orbitals. The two carbon atoms form a triple bond between them, which consists of one sigma bond and two pi bonds. The sigma bond is formed by the overlap of the sp hybrid orbitals, while the pi bonds are formed by the side-by-side overlap of the unhybridized p orbitals.
The hybridization of the carbon atoms in acetylene leads to a linear arrangement of the atoms. The two carbon atoms are directly bonded to each other, and each carbon atom is also bonded to a hydrogen atom. This results in a molecule with a linear geometry, where the bond angles between the atoms are 180 degrees. The linearity of the molecule is a direct consequence of the sp hybridization, which causes the electron pairs to be as far apart as possible, thereby minimizing repulsion.
The linearity of C2H2 is not only predicted by theory but is also supported by experimental evidence. Spectroscopic studies, such as infrared spectroscopy, Raman spectroscopy, and X-ray crystallography, have all confirmed the linear structure of acetylene. The bond lengths and angles observed in these studies are consistent with the predictions of the VSEPR theory.
Furthermore, the linear geometry of acetylene has significant implications for its chemical reactivity. The triple bond between the carbon atoms is quite strong, making acetylene a relatively stable molecule. However, the molecule is also quite reactive due to the presence of the pi bonds, which are more easily accessible for reactions than the sigma bond.
In summary, acetylene (C2H2) is indeed a linear molecule. Its linear geometry is a result of the sp hybridization of the carbon atoms, which leads to a molecular shape where the electron pairs are as far apart as possible to minimize repulsion. This linear arrangement is confirmed by various experimental techniques and has important implications for the molecule's stability and reactivity.

Based on VSEPR Theory (Valence Shell Electron Pair Repulsion Theory) the electron clouds on the atoms around the C will repel each other. As a result they will be pushed apart giving the molecule a linear molecular geometry or shape. The C2H2 bond angle will be 180 degrees since it has a linear geometry.Dec 6, 2013
