ANSWER

Read the passage given below and answer the following questions: The properties of the solutions which depend only on the number of solute particles but not on the nature of the solute are called colligative properties. Relative lowering in vapour pressure is also an example of colligative properties. For an experiment, sugar solution is prepared for which lowering in vapour pressure was found to be 0.061 mm of Hg. (Vapour pressure of water at 200C is 17.5 mm of Hg).

Gibbs's free energy is related to the electromotive force of the cells. When charge flows through the galvanic cell in a reverse reaction, the maximum amount of work is done by the galvanic cell. The amount of this reversible work done by the cell results in a decrease of Gibbs free energy.

Transition elements (also known as transition metals) are elements that have partially filled d orbitals. IUPAC defines transition elements as an element having a d subshell that is partially filled with electrons, or an element that has the ability to form stable cations with an incompletely filled d orbital.

ANSWER

Glucose and sucrose are soluble in water but cyclohexane and benzene (simple six membered ring compounds) are insoluble in water. Explain.

Posted by Akshit Mohanty 2 years, 3 months ago

CBSE > Class 12 > Chemistry

3 answers

Shanika Sharma 2 years, 2 months ago

The solubility of a solute in a given solvent follows the rule 'Like dissolves like'. Glucose contains five and sucrose contains eight −OH group. These −OH groups form H-bonds with water. As a result of this extensive intermoleeular H-bonding, glucose and sucrose are soluble in water. on the other hand, benzene and cyclohexane do not contain −OH bonds and hence do not form H-bonds with water. Moreover, they are non-polar molecules and hence do not dissolve in polar water molecules.
