Interpretation:
Chloromethane is a polar molecule while carbon tetrachloride is non polar though chloromethane has only one polar C-Cl bond while carbon tetrachloride has four polar C-Cl bonds. Explain.
Concept Introduction:
A molecule has polar bond if there is electro-negativity difference between to bonded atoms. The electro-negativity is the tendency to pull share pair of electrons towards itself. The polarity is created if the difference in the electro-negativity is greater than 0.4.
Dipole exists in a molecule if it has polar bond. Dipole moment is the measure of polarity and it is a vector quantity (depends upon the direction).

Draw a three-dimensional representation of each molecule and indicate the Direction of it.s polarity.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.
