- A student wants to determine the melting point of water as part of an investigation into the strength of electrostatic forces. The student considers determining the freezing point of water instead. Is this a valid option? O No, it is not because the freezing point is not related to electrostatic forces. O No, it is not because the freezing point is not related to the melting point. O Yes, it is; and determining the freezing point is likely to be more accurate. O Yes, it is; but determining the freezing point is likely to be more difficult.arrow_forwardIs acetone polar or nonpolar? Will NaCl dissolve in it?arrow_forwardWhich of the following is FALSE about the water molecule? A) The H atoms bear the partial positive charge. Intermolecular forces among water molecules are the least extensive when it is in liquid B form. (c) The atoms comprising the water molecule are covalently bonded with one another. D Its molecular geometry is not linear.arrow_forward
- Determine the electronegativity difference and the molecular polarity (P for polar and NP for nonpolar) of the following compounds then further classify the dominant intermolecular forces of attraction exhibited. Place HB for hydrogen bonding, LDF for London dispersion force, DD for dipole-dipole and ID for the ion-dipole bond. The first one is already done for you. 1.78 | P | hydrogen fluoride | HB 02 C2H6 NH4 H2O I2 HFarrow_forwardHow many bonding pair/lone pair of electons surround the hydrogen atom in a water molecule?arrow_forward3,Which of the following happens when solid calcium chloride dissolves in water? a, the attractive forces between water and calcium and chloride ions are overcome by the attractive forces between calcium and chloride ions. bThe attractive forces between the calcium and chloride ions are overcome by the attractive forces between the water and calcium and chloride ions. c, The negative pole of the water molecule is attracted to the chloride ions. d, The positive pole of the water molecules is attracted to calcium ions.arrow_forward
- In general, which of the following type(s) of solid(s) would exhibit the greatest solubility in a polar solvent?arrow_forwardWhich of the following is TRUE about the relationship between temperature and Kinetic energy (KE)? Select the correct response: KE decreases with increasing temperature. OTemperature and KE do not correlate The cooler it is, the more excited the molecules are. KE Increases with increasing temperature.arrow_forwardWhich of the drawings below best represent the hydrogen bond intermolecular force (IMF)? H H H-F (1) (2) H-H -- (3) (4)arrow_forward
- In weak chemical bonds, an example of it is Hydrogen bonds. What does it mean when they say, "The H atom forms one covalent bond and a second weaker bond"?arrow_forward3. What is the implication of molecular polarity in predicting the intermolecular forces of attractions present between particles?arrow_forwardComplete this statement: "The bonding between atoms within a water molecule is called A. The attraction between water molecules is a general type of molecular interaction called B __. A specific type of this molecular interaction that involves hydrogen is called Carrow_forward
