Witryna24 mar 2024 · Acetone molecules have weak intermolecular forces. that is called dispersion forces. acetone molecules are attraction by London dispersion forces and dipole dipole interaction. this molecules has dipole, so it is create dipole dipole forces. there is no hydrogen bonding because hydrogen bonding is not directly attachment to … Witryna15 sie 2024 · Example \(\PageIndex{1}\) Arrange ethyl methyl ether (CH 3 OCH 2 CH 3), 2-methylpropane [isobutane, (CH 3) 2 CHCH 3], and acetone (CH 3 COCH 3) in order of increasing boiling points.Their structures are as follows: Given: compounds Asked for: … WitrynaAcetone is a polar molecule because it has a polar bond, and the molecular structure does not cause the dipole to be canceled. Step 1: Polar bonds? C is slightly more electronegative than H (2.4 vs. 2.1). O is the second most electronegative element on the table. It is more electronegative than C (3.5 vs. 2.4). The C-O bond is polar. highest rated residential zero turn mower
