(a)
Interpretation:
The given statements are true or false should be determined.
Concept Introduction:
Polarity of any molecule depends on electronegativity of atoms that forms covalent bonds. Depending upon the difference in electronegativity of atoms, polar or nonpolar molecule is determined. Polar molecule has electronegativity between 0.5 and 1.4 whereas in nonpolar molecule, it is less than 0.5.
(b)
Interpretation:
The given statements are true or false should be determined.

- 3-89 Is it possible for a molecule to have no polar bonds and yet have a dipole? Explain.arrow_forward3-78 Nitrous oxide, N20, laughing gas, is a colorless, nontoxic, tasteless, and odorless gas. It is used as an inhalation anesthetic in dental and other surgeries. Because nitrous oxide is soluble in vegetable oils (fats), it is used commercially as a propellant in whipped toppings Nitrous oxide dissolves in fats. The gas is added under pressure to cans of whipped topping. When the valve is opened, the gas expands, thus expanding (whipping) the topping and forcing it out of the can. (a) How many valence electrons are present in a molecule of N20? (b) Write two equivalent contributing structures for this molecule. The connectivity in nitrous oxide is NNO. (c) Explain why the following is not an acceptable contributing structure:arrow_forward3-109 Until several years ago, the two chlorofluorocarbons (CFCs) most widely used as heat transfer media in refrigeration systems were Freon-li (trichloro fluoromethane, CC13F) and Freon-12 (dichiorodi fluoromethane, CCl2F2).
