1 mole of glucose was dissolved in 1 kg of water ethanol ether benzene sepretaly which show benzene as solvent in solution how to solve this question plz tell

To tackle the question of how 1 mole of glucose behaves when dissolved in different solvents, particularly focusing on benzene, we need to consider several factors including solubility, molecular interactions, and the nature of the solvents involved. Let’s break this down step by step.

Understanding Solubility

Solubility refers to the ability of a solute (in this case, glucose) to dissolve in a solvent (like water, ethanol, ether, or benzene). The principle of "like dissolves like" is crucial here. This means that polar solutes tend to dissolve well in polar solvents, while non-polar solutes are better suited for non-polar solvents.

Properties of Glucose

Glucose is a polar molecule due to its hydroxyl (-OH) groups, which can form hydrogen bonds with water and other polar solvents. This characteristic makes glucose highly soluble in water and ethanol, which are both polar solvents.

Examining the Solvents

• Water: A highly polar solvent, excellent for dissolving polar substances.
• Ethanol: Also polar, and can dissolve glucose effectively due to its ability to form hydrogen bonds.
• Ether: Generally non-polar, thus it would not dissolve glucose well.
• Benzene: A non-polar solvent, which typically does not dissolve polar substances like glucose.

Why Benzene is Not a Suitable Solvent for Glucose

When glucose is placed in benzene, it is unlikely to dissolve significantly. The non-polar nature of benzene means it cannot effectively interact with the polar glucose molecules. The lack of hydrogen bonding opportunities in benzene prevents glucose from breaking apart and dispersing in the solvent.

Practical Implications

In a laboratory setting, if you were to mix 1 mole of glucose with 1 kg of benzene, you would observe that most of the glucose remains undissolved at the bottom of the container. This is a clear demonstration of the solubility principle. In contrast, if you were to perform the same experiment with water or ethanol, you would find that the glucose dissolves readily, indicating strong interactions between the solute and solvent.

Conclusion on Solvent Selection

In summary, when considering the solubility of glucose in various solvents, benzene stands out as an ineffective choice due to its non-polar characteristics. For successful dissolution of glucose, polar solvents like water or ethanol are the best options. This understanding is crucial in fields such as chemistry and biochemistry, where solvent choice can significantly impact reactions and processes.
