- There are three flask they are all 1.00L flask a is NH3 flask B is NO2 flask c is N2 which flask are the molecules least polar and therfore most ideal in behaviorarrow_forwardExplain the two-step procedure for Polarity of Molecules ?arrow_forwardBased on the formula and geometries of the substances(water, ethyl alcohol, vinegar and acetone), are the molecules that can hold more drops on the coin polar or non polar? What about those that took longer to evaporate? Explain.arrow_forward
- Mineral oil consists of a mixture of hydrocarbons (compounds consisting of just carbon and hydrogens) consisting of nine or more carbon atoms. An example of a large hydrocarbon is eicosane which has a molecular formula of C20H42. The boiling point of eiconsane is 343.1 oC. Why is the boiling point of this nonpolar molecule so much higher than the boiling point of water (a polar molecule with a boiling point of 100 oC). In your answer, be sure and include the role of specific intermolecular attractive forces for each molecule.arrow_forward2(a) Provide the Lewis structures for both CH3OH and C2H3Cl. 2(b) What is the largest bond angle among all the bond angles in CH3OH and C2H3Cl? Listthe three atoms making this largest bond angle, and estimate the value of the angle.2(c) What intermolecular forces are present(i) between CH3OH molecules?(ii) between C2H3Cl molecules?arrow_forwardHow do chemists predict the shapes of molecules? A. Due to the attraction between electrons, valence electrons will be arranged as close to each other aspossible. B. Due to the repulsion between electrons, valence electrons will be arranged as far apart from eachother as possible. C. Due to the repulsion between electrons, valence electrons will be arranged as close to each other aspossible. D. Chemists can't predict the shape of molecules, because the attractive forces between valenceelectrons are unpredictable.arrow_forward

Group of answer choices CCl4, carbon (IV) chloride CrCl3, chromium (III) chloride CuO, copper (II) oxide FeO, iron (II) oxide 3. The strongest interactions between molecules of potassium oxide are dipole-dipole interactions hydrogen bonds dispersion forces ionic bonds nonpolar covalentarrow_forwardConsider the hypothetical molecule PHFBr, in which the phosphorus atom is in the center.This molecule has exactly one central atom. c) According to VSEPR Theory, the molecular geometry is: ___________________d) Is the P-F bond ionic, polar covalent, or nonpolar covalent? How did you decide?e) Do you expect the PHFBr molecule to be polar or nonpolar? Justify your answer.f) Which of the following intermolecular forces should be considered between PHFBrmolecules: Dipole-dipole force, ion-dipole force, London Dispersion Force, or Hydrogenbonding? List all the forces that are appropriate below.arrow_forwardYou come across a bottle in the stock room labeled CHCl3 a.Draw the Lewis dot structure of the molecule b.Identify the molecular geometry of the molecule c.dentify if the molecule is polar or non-polar. d.Do you expect this molecule to interact more with water (H2O) or methane (CH4)?Explain why.arrow_forward
