Draw all C_4H_10 isomers and explain which of them has the higher boiling point? C) larger hydrogen-bond forc, Arrange the following compounds from highest boiling point to lowest boiling point and explain your answer on the basis of whether the substance is polar, nonpolar, ionic, metallic, or has hydrogen bonding. Intermolecular forces control the physical properties like melting point and boiling point. Why? Its density is 1.435 g/mL and its vapor pressure at 20C is 124 mm Hg. Answer 4: E. There are intermolecular forces between neutral non-polar atoms called London dispersion (Van der Waals) interactions. Determine the intermolecular forces in the compounds and then arrange the compounds according to the strength of those forces. You are correct; since the dipoles cancel out, they each have only London forces. What phase changes will take place when water is subjected to varying pressure at a constant temperature of 0.005 C? At 40 C? B) viscosity B) dispersion forces, dipole-dipole, and ion-dipole Explain. Which of the following has dispersion forces as its only intermolecular force? e) all, The shape of a liquid's meniscus is determined by ________. C) C6H13NH2 What are their states at room temperature? (a) evaporate benzene (C6H6) (b) boil chloroform (CHCl3) (c) boil liquid ammonia (NH3) 1. How does the strength of intermolecular forces affect a liquids vapor pressure? D) natural gas flames don't burn as hot at high altitudes 2. In contrast, each oxygen atom is bonded to two H atoms at the shorter distance and two at the longer distance, corresponding to two OH covalent bonds and twoOH hydrogen bonds from adjacent water molecules, respectively. A: Molecule is made up of two or more than two atoms. Consequently, even though their molecular masses are similar to that of water, their boiling points are significantly lower than the boiling point of water, which forms four hydrogen bonds at a time. Ammonia (NH3), methylamine (CH3NH2), and ethylamine (CH3CH2NH2) are gases at room temperature, while propylamine (CH3CH2CH2NH2) is a liquid at room temperature. B) hydrogen bonding Provide a molecule and discuss its specific intermolecular forces and the physical properties that can be expected as a result of th.
