Answer. It is colorless and highly flammable. Indicate the bond angles and specify if they are non-ideal. Acetone, or propanone, is an organic compound with the formula (CH 3) 2 CO. One end is positive ( due to the H's) and another end is negative (due to the O). Was the final answer of the question wrong? Molecular Geometry of Dichloromethane Similarly, one chlorine atom is to the right of Carbon and the other one is one the downward position of the central atom. Your bond polarity findings are also accurate in saying both bonds are covalent and that the bond between O and C is a little less covalent then C and H.-Kaleigh Crowell Period A, Intermolecular forces: You correctly identified your intermolecular forces. Acetone is miscible with water and serves as an important organic solvent in its own right, in industry, home, and laboratory. Molecular geometry is the name of the geometry used to describe the shape of a molecule. Lastly, I thought the ad was sucessful in giving all the information needed about acetone but be careful giving information on how dangerous it is as well. For the Lewis structure for Acetone, calculate the total number of valence electrons for the Acetone molecule. Overall, I thought this was a very good blog.--Sam Travelyn, Overall Appearance: The general appearance of this blog is very nice. If LP–BP repulsions were weaker than BP–BP repulsions, what would be the effect on the molecular geometry of BrF 5? Acetone is a polar molecule. You were accurate in saying that the molecule is triangular planar in an AX3 form. The geometric shape of acetone (CH3)2COistrigonal planar. The brightness of this ad is attractive and helps to sell the product. The central carbon shares a double bond with the Oxygen and a single bond with the other Carbons. one year ago, Posted 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, Posted The white ball repsesent the Hydrogens. The uneven distribution of charges througout the molecule makes it polar. The color choices fit well together, along with the font style and type. 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. 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. Molar mass of (CH3)2CO = 58.07914 g/mol. Along with the shape the correct bond angle or 120 was expressed and displayed in a picture. Let's look at another intermolecular force, and this one's called hydrogen bonding. 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. Get it solved from our top experts within 48hrs! IR spectra and properties of solid acetone, an interstellar and cometary molecule Reggie L. Hudsona,⁎, Perry A. Gerakinesa, Robert F. Ferranteb a Astrochemistry Laboratory, NASA Goddard Space Flight Center, Greenbelt, MD 20771, USA b Chemistry Department, U.S. 20 hours ago. Figure 8.18: (a) In a bonding pair of electrons, the electrons are shared by two nuclei. Molecular Geometry VSEPR Model: Geometries ... •Acetone . 2 years ago, Posted See the answer When determining the molecular geometry of Acetone (C3H6O), do you only consider the central carbon and it's bonds with the other two carbons and the oxygen, or are the three hydrogens on either end taken into account? 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. Acetone is a member of the Ketone family of organic compounds. The molecular geometry is the shape of the molecule. Were the solution steps not detailed enough? - Mr Acetate, Thank you for the further info about Acetone! Useful info . The molecule consists of one carbonyl group surrounded by two methyl groups on both sides. 4 years ago, Posted it has the tetrahedral molecular geometry for the central carbon It is a nonpolar molecule. These are: An electrostatic attraction between the poitive end of a dipole and the negative end of another dipole. by | Jan 2, 2021 | Uncategorized | 0 comments | Jan 2, 2021 | Uncategorized | 0 comments (i) C1 (ii) C2 (iii) C3. Acetone is toxic if ingested. 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. It evaporates easily, is flammable, and dissolves in water. Ask a Similar Question. d) The structure shown at the left is the known geometry for acetone. It is a colorless liquid with a distinct smell and taste. In the case of acetone, it's slightly more polar than water. Acetone is a manufactured chemical that is also found naturally in the environment. It was also informative that you included the definition of hydrogen bonding, but explained why it didn't work between to acetone molecules because neither F, O, or N where present. (Hide this section if you want to rate later). (Rate this solution on a scale of 1-5 below), Log into your existing Transtutors account. The molecule C3H6O, also known as Acetone, is Triangular Planar. The chemical synthesis however was done in solution at ambient or low temperatures, a game … Your information about acetone is completely accurate. Those Carbons both have bonds with three Hydrogens, which have a positive charge. Thanks for sharing. It is often used as solvent to dissolve other substances such as paint, fingernail polish and glues.
