14. ### Molecular Polarity Analysis Exercise**Instructions:** Use these molecules to answer questions 14-17.#### Diagram Descriptions:**Molecule A:** - Structure: A silicon (Si) atom is at the center bonded to four fluorine (F) atoms. Each F atom has three lone pairs of electrons, represented by six dots around each F. This is a tetrahedral shape. **Molecule B:** - Structure: The molecule is composed of two carbon (C) atoms connected by a single bond, with hydrogen (H) atoms attached to each carbon. One of the carbons is also bonded to an oxygen (O) atom with two lone pairs of electrons. The overall shape is linear around the C=C double bond.**Molecule C:** - Structure: Three carbon (C) atoms are connected in a chain. The middle carbon atom is double-bonded to an oxygen (O) atom with two lone pairs. The end carbon atoms are also bonded to hydrogen (H) atoms. The shape includes linear and planar elements, with a central C=O bond.#### Question 14:**Which molecule(s) is/are polar?****Options:**- A) Molecule A- B) Molecule B- C) Molecule C- D) Molecule B and C- E) Molecule A and C---### Explanation on Polarity:When determining the polarity of a molecule, consider the shape and the distribution of electronegative atoms or groups, such as fluorine or oxygen. Molecules with an asymmetrical distribution may have dipole moments resulting in polarity.

Constants Periodic Table A sample of a liquid substance called jojane- named after the narcissitic scientist Dr. Joey Negdirf who discovered the substance- was brought back to Earth following a five year mission exploring the Andromeda galaxy. In their lab on earth, Dr. Negdirf's team conducted a number of experiments to determine the physical properties of the substance. Part A Using the Dumas method to determine the molar mass of a volatile liquid, a sample of jojane was vaporized in a 2.000 L vessel and heated to 401.6 K at 1.150 bar. The mass of the vapour in the vessel was 5.106 g. Determine the the molar mass of the compound. 60.10 g mol-1 O 88.14 g mol-1 O 72.09 g mol-1 O 74.12 g mol-1
