Complete step by step answer: The given compound methanol i.e. 0.10 m HCl iv. For each of the molecules below, list the types of intermolecular force which act between pairs of these molecules. CH3CH2OH has the strongest intermolecular forces because it has the strongest dipole–dipole forces due to hydrogen bonding. Therefore, H-bonding 3. dispersion 4. dipole dipole . There are two forces between molecules now available. tutor. The major intermolecular forces would be dipole-dipole forces and London dispersion forces. The oxygen atom is binded only to carbon and no hydrogen. The molecule that provides the electron rich site to which the hydrogen is attracted is called an acceptor. 10. CH3COCH3. (d) acetic acid, CH 3 COOH H is bonded to an electronegative element (O-H bonds). We’re being asked to identify the intermolecular forces present in CH 3 CH 2 OH. Recall that there are several types of intermolecular forces: 1. Ion-dipole interaction – occurs between an ion and a polar covalent compound. 2. Hydrogen bonding – occurs in compounds where hydrogen is directly connected to an electronegative element such as N, O, or F. 3. CH4 b.) IMF between polar molecules. imf with polar molecules containg a HN, HO OR HF bond (CH is NOT hydrogen bonding) Problem: Methanol (CH3OH) has a higher vapor pressure than octanol (C 8H17OH) because 1. methanol is non-polar and octanol is polar2. intermolecular forces.
