A plough or plow (US; both / p l aÊ /) is a tool or farm implement used in farming for initial cultivation of soil in preparation for sowing seed or planting to loosen or turn the soil. Ploughs were traditionally drawn by working animals such as horses or cattle, but in modern times are drawn by tractors.
Nonpolar molecule. Definition. noun, plural: nonpolar molecules. A molecule with nonpolar bonds or with polar bonds but arranged symmetrically. Supplement. Polar bonds may occur in both polar and nonpolar molecules.However, the polar bonds in nonpolar molecules are arranged symmetrically causing dipoles to cancel out each other. As a result, nonpolar molecules have no net dipole.efinition. noun, plural: nonpolar molecules. A molecule with nonpolar bonds or with polar bonds but arranged symmetrically. Supplement. Polar bonds may occur in both polar and nonpolar molecules.
The bonds are arranged symmetrically around the central C atom and because the bond dipoles cancel, the molecule is non-polar. QUESTION (2011:1) (c) For each of the following molecules: (i) Circle the phrase that describes whether the molecule contains a polar bond or a non-polar bond.Cl 4 nonâpolar molecule The molecule is tetrahedral, due to 4 electron repulsions around the central C atom. The CâCl bond is polar, due to the difference in electronegativity of C and Cl. As these polar bonds are symmetrical about the C atom in CCl 4, the effect of them is cancelled, so the molecule is non-polar.
