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. The dipole in CH3NH2 can H-bond while that in ...
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 ...
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 =
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 -.
Jan 8, 2020 · Answer: n-butyl chloride is the isomer of C4H9Cl which will have lowest boiling point. JAI SHRI RAM
Nov 12, 2020 · Boiling point of juice , soy sauce , milk , soda are as follows: 1. Boiling point of apple juice is 160 degree Celsius or 320 degree Fahrenheit. 2. Boiling point of soy sauce is not determined as different companies use different key ingredients to prepare the soy sauce . 3.
Sep 26, 2020 · The boiling point of nitrogen is very low even though the bond between the atoms in a nitrogen molecule is very strong. Suggest an explanation. ... however the intermolecular forces between the nitrogen molecules are very weak. thus they are easily overcome wih little energy therfore leading o a very low boiling point.
Jan 29, 2019 · Boiling point elevation constant for a solvent or ebullioscopic constant. Explanation: We know that, Tb = Kb m. where m = 1, Tb = Kb. Thus, boiling point elevation constant is equal to the elevation in boiling point when 1 mole of a solute is dissolved in 1 kg of solvent. It is also called ebullioscopic constant.
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 ...
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.
