Dec 15, 2018 · has the highest boiling point. Explanation: The expression of elevation in boiling point is given as: where, = Elevation in boiling point. i = Van't Hoff factor = change in boiling point = boiling point constant. m = molality. For the given options: Option 1: 1 m glucose. Value of i = 1 (for non-electrolytes) So, molal concentration will be =
Jan 17, 2019 · The dipole in CH3NH2 can H-bond while that in CH3F cannot. Therefore, CH3NH2 has the stronger interactions and the higher boiling point. (c) Both CH3OH and CH3CH2OH can H-bond but CH3CH2OH has more CH bonds for greater dispersion force interactions. Therefore, CH3CH2OH has the higher boiling point. chevron right.
Jan 28, 2020 · What is boiling point: The boiling point of a liquid is the temperature at which it begins to boil. For example, at a pressure of 1 atm, the boiling point of water is 100°C. The boiling point of a liquid is determined by three factors: temperature, air pressure, and the liquid's vapour pressure. Boiling point of: SnCl₄ - 114.15 °C; Gecl₄ ...
Aug 29, 2017 · Pentane has 3 structural isomers -. n-pentane => CH3-CH2-CH2-CH2-CH3. isopentane => CH3-CH2-CH (CH3)2. neopentane => C (CH3)4. Due to branching, molecules get contracted and associated van der Waal's forces gets weakened. Thus boiling point decreases with increase in branching. Therefore, boiling point of pentane isomers is in order -.
Feb 28, 2023 · Obviously, elevation in boiling point is a colligative property. Hence, the required answer is, option (1) Both A and R are true and R is the correct explanation of A. Lowering of vapour pressure elevates the boiling point, which is directly proportional to the mole fraction of solute in the solution. Therefore it is a colligative property.
Jan 13, 2019 · question. If the enthalpy of vaporization delta H and entropy of vaporization delta S are known (for very many substances they are available in tables), set the Gibbs free energy of vaporization delta G = delta H minus T delta S = 0. Then the temperature of the boiling point is T = delta H/delta S. Trouton's rule, which states that the entropy ...
Jan 8, 2020 · Answer: n-butyl chloride is the isomer of C4H9Cl which will have lowest boiling point. JAI SHRI RAM
Apr 27, 2017 · Answer: The 'temperature of a substance' remains constant during its melting and boiling point because the change in any state of matter as n solid to liquid or the liquid to a gas involves crossing the 'latent heat of fusion' which causes a change in the intermolecular spacing of the molecules in the substance.
Oct 22, 2021 · The increase in the boiling point of a solvent on the addition of solute is referred to as boiling point elevation. It is given by the formula: where is the boiling point elevation, is the boiling point elevation constant and m is the molality of the solution.
Apr 20, 2023 · Elevation in boiling point: Where, is the boiling point of the solvent in pure form and is that of a dilute solution prepared by dissolving a non-volatile solute in the solvent. Here: = 100 [boiling point of water] = 373 K = 105.2 [Given] = 378.2 K. Substitute these values in the equation of . = 378.2 - 373 = 5.2 K
