This structure is correctly identified as an AX3 and your angles are correct. Indicate the bond angles and specify if they are non-ideal. One end is positive ( due to the H's) and another end is negative (due to the O). The molecule C3H6O, also known as Acetone, is Triangular Planar. I like the way you showed your results, instead of in paragraph form you listed them in a easier was to follow. The central carbon shares a double bond with the Oxygen and a single bond with the other Carbons. It has a role as a polar aprotic solvent and an EC 3.5.1.4 (amidase) inhibitor. 4 years ago, Posted The molecule, being a AX3 Triangular Planar was mentioned multiple times and explained so that anyone could understand. The color choices fit well together, along with the font style and type. It is easy to access and read. The bonds between the central Carbon to the other Carbons are single. The carbonyl carbon is trigonal planar because it is sp2 hybridizedso the bond angle is... 0 and the other carbons are sp3 hybridized and therefore tetrahedral thusthe bond angles are 109.5. Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around a central atom, of a molecule from an examination of the number of bonds and lone electron pairs in its Lewis structure. Molecular Structure of Acetone Whenever you see the term solvent, think of the phrase, ''like dissolves like.'' Everything is very organized and easy to find. Its Lewis Structure is: The red ball represents Oxygen. The uneven distribution of charges througout the molecule makes it polar.

I am getting bored, please fchat with me ;) ;) ;) …████████████████████████████████████████████████████████████████████████████████████████████████. Its Lewis Structure is: This atom is an AX3 or a Triangular Planar because there are no unshared pairs on the central atom and the central atom has three other atoms haning off of it. However, if this molecule came across a molecule such as HF there would be hydrogen bonding because the Hydrogen of Acetone would form a bond with the Flourine of HF. The VSEPR model assumes that electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between these electron pairs by maximizing the distanc… Was the final answer of the question wrong?

Ferranteb a Astrochemistry Laboratory, NASA Goddard Space Flight Center, Greenbelt, MD 20771, USA b Chemistry Department, U.S. Molecular geometry is the name of the geometry used to describe the shape of a molecule. From an electron-group-geometry perspective, GeF 2 has a trigonal planar shape, but its real shape is dictated by the positions of the atoms. Acetone is the most simple ketone, thus it has is formed by a three carbon chain which has two of the hydrogen from second carbon substituted by an oxygen double bound with the carbon atom. Acetone is a manufactured chemical that is also found naturally in the environment. The molecule consists of one carbonyl group surrounded by two methyl groups on both sides. For the Lewis structure for Acetone, calculate the total number of valence electrons for the Acetone molecule. I thought it was ver informative and I did not know acetone was in nail polish remover, which was very cool to learn. You were accurate in finding the intermolecular forces of acetone as well.
