UpStudy Free Solution: For the molecule $$	ext { C} _ 2	ext { H} _ 2$$ (acetylene), each carbon atom is considered a central atom. To determine the number of regions of electron density around each carbon atom according to VSEPR theory, we need to consider the bonds: - Each carbon atom in $$	ext { C} _ 2	ext { H} _ 2$$ forms a triple bond with the other carbon atom and a single bond with a hydrogen atom.- In VSEPR theory, a triple bond counts as one region of electron density, and a single bond also counts as one region of electron density. Therefore, each carbon atom has:- One region of electron density from the triple bond with the other carbon atom.- One region of electron density from the single bond with the hydrogen atom. This gives a total of 2 regions of electron density around each carbon atom. So, the number of regions of electron density around each central atom in $$	ext { C} _ 2	ext { H} _ 2$$ is 2. Supplemental Knowledge The Valence Shell Electron Pair Repulsion (VSEPR) theory is a model used to predict the geometry of individual molecules based on the extent of electron-pair electrostatic repulsion. According to VSEPR theory, the shape of a molecule is determined by the number of regions of electron density (bonds and lone pairs) around a central atom. These regions arrange themselves as far apart as possible to minimize repulsion. In acetylene ($$	ext { C} _ 2	ext { H} _ 2$$), each carbon atom forms:- A triple bond with another carbon atom.- A single bond with a hydrogen atom. Each type of bond (single, double, or triple) counts as one region of electron density. Therefore, for each carbon atom in $$	ext { C} _ 2	ext { H} _ 2$$:- The triple bond with the other carbon counts as one region.- The single bond with hydrogen counts as another region. Thus, each carbon atom has two regions of electron density. This arrangement leads to a linear molecular geometry around each carbon atom because two regions of electron density will position themselves 180 degrees apart to minimize repulsion. Understanding molecular geometry can be tricky, yet essential for mastering chemistry concepts.
