In a particular compound, we can have two types of common bonds: An ionic bond, which consists of a metal and a nonmetal with a high electronegativity difference A polar covalent bond which consists of two nonmetals with low electronegativity difference A nonpolar...
What is Polarity? - A polar molecule is one that contains positive and negative poles. In a polar molecule, a dipole moment exists. In a nonpolar molecule, no dipole moment exists. More on Polarity and its types @ BYJU’S.
When growth hormone binds to an enzyme-linked receptor: (a) G proteins form a cascade of molecules and are phosphorylated (b) the enzyme portion of the receptor is dephosphorylated (c) the receptor is activated and phosphor...
Bond Model: This model takes typical bond purchase inputs (purchase price, par value, interest rate, and life to maturity) and calculates bond cash flows, current yield, and yield to maturity. Breakeven Analysis: This model is an example of a breakeven analysis of a set of revenue levels...

Draw the Lewis structure to determine the number of bonding electron pairs and number of nonbonding pairs on the central atom (a double or triple bond counts as a single electron pair when using VSEPR theory). Arrange the bonding and nonbonding electron pairs around the central atom in a geo...
Saponifying plant-derived oleoresin, washing with sodium chloride solution, washing the resin with non-polar solvent such as hexane, pentane, heptane and p... A simple and economic method of extracting free xanthophylls from plant material, particularly marigold petals and boxthorn berries, is descr...
This is attributed to the modulation of the nonradiative rates associated with the excited-state intermolecular hydrogen bonding between the pigment and the polar solvents. We obtained a high partition constant at W0 = 0 (W0 = [core solvent]/[AOT]) which is certainly due to the hydrogen ...
Polar Molecules:If the centre of mass of positive charge doesn’t coincide with the centre of mass of negative charge then it is known as a polar molecule. Non-Polar Molecules:If the center of mass of positive charge coincides with the center, charges, s of negative charge then it is kn...
