state whether the solutes and solvents of the following combinations are miscible or immiscble: nonpolar solute + polar solvent. No, octane is a non-polar molecule. also, if you absolutely need to draw one, what is the easiest way to go about drawing a more advanced molecule like octane? Ans: In CO 2 the two bond moments point in opposite directions and are of equal magnitude. Geometrical Shape: The shape of a molecule is an important parameter to check whether a molecule is polar or not. Octane (C_8H_18) is a hydrocarbon, an organic compound consisting entirely of carbon and hydrogen atoms. And the nonpolar molecules have zero dipole moment. If an equilibrium mixture contains 0.44 M IBr and 1.1×10−2 M I2, what is the molar concentration of Br2? ... C8H18: C7H16. SInce a polar molecule must have polar bonds, let's look at the polarity of the C"-"H bond in order to determine if octane could be considered polar. Acetone is a molecule made carbon, hydrogen and oxygen. predict if the following are miscible or immiscible with octane, C8H18: CHCL3. Polar bonds are formed from an uneven distribution of electrons. Mathematically, it is the product of the charge on atoms and the distance between them. For a particular isomer of C8H18, the following reaction produces 5104.1 kJ of heat per mole of C8H18(g) consumed, under standard conditions. ... Is it polar or nonpolar? Answer this question + 100. Nonpolar bonds are formed when two atoms share an equal number of electrons. NH2OH and C8H18 Is it polar or nonpolar? 37. Hello, for octane (C8H18), how can you tell whether or not it is polar or non-polar without drawing a lewis structure diagram? A) NH2OH and C8H18 will form homogeneous solution when combined. Examples of nonpolar bonds include fats and oils. Be the first to answer this question. B) NH2OH and C8H18 will not form homogeneous solution when combined. Bond polarity is determined using the electronegativity values of the two atoms that form the bond. There are no answers yet. immiscible. Nonpolar bonds are usually hydrophobic or insoluble in water. Therefore, they cancel. is nonpolar, but OCS is polar. Nonpolar: C8H18 (octane) Nonpolar: carbon disulfide: Nonpolar: carbon tetrabromide: Nonpolar: carbon tetrachloride: Nonpolar: carbon tetrafluoride: Nonpolar: carbonate ions: Nonpolar: cbr: ... NH4Br is Nonpolar I'll tell you the polar or nonpolar list below. C8H18 is octane, a simple hydrocarbon. miscible. Draw a Lewis structure for PF 5 immiscible. Because neither carbon-carbon nor carbon-hydrogen bonds are polar, this compound is non-polar (as are all hydrocarbons). polar solute + nonpolar solvent. In OCS, even though the two bond moments point in opposite directions, they are not of the same magnitude and do not cancel. The polar molecule always has a non zero dipole moment. Answer Save. It is colorless and highly flammable.
