9. Which of the following molecules can form hydrogem bonde? L CH,NH IL CH,CH,CH OH a. Ionly b. Il only c. IlI only d. I and I e. All of these Determine the intermolecular boiling point. 10. ar forces present for each substance and predict which would have the higher SClh or SBr Both have London dispersion dipole-dipole. b. Both have London dispersion and dipole-dipole. c. Both have London dispersion and dipole-dipole, but only and dipole-dipole. Therefore SBr, has a higher bp. Therefore SC, has a higher bp. SCl2 has a higher bp. d. Both have only London dispersion forces. Therefore SCl, has a higher bp. e. Both have only London dispersion forces. Therefore SBry has a higher bp I1. Arrange the following molecules in order of increasing viscosity- A commercial bleaching solution contains 3.62% sodium hypochlorite NOCL What is the mass of NaOCI present in a bottle that contains 4.50 x 10 g of bleaching solution? a. 8.04 x 10 g NaOCI b. 0.0804 g NaOCI c. 163 g NaOCI d. 1.24 x 10' g NaOCI 12. 1.63 × 104 g NaOCl 13. How many grams of glucose (C&H120s;) must be dissolved in 750 g of ethanol (C,H,OH) to prepare a 0.54 solution? MM(C&H120;)- 180.15 g/mol a. 2.27 x 103 g glucose b. 73.6 g glucose c. 131 g glucose d. 248 g glucose e. 441 g glucoseExplanation / Answer
9) e , All can form hydrogen bond. So all compound present in option are water soluble
10) e , SBr2hhas high boiling point because down the group boiling point is increases in periodic table.
11) b , Viscosity increases on increasing the carbon number.
12) c, 3.32g in 100g
X in 4500g
X=163g
13) e
