Which molecule would be most soluble in water?
|
|
Solid iodine, I2(s)
|
|
|
Glucose, C6H12O6(s)
|
Explanation:
Detailed explanation-1: -Consequently, glucose is very soluble in water (91 g/120 mL of water) but essentially insoluble in nonpolar solvents such as benzene.
Detailed explanation-2: -The hydroxyl groups in glucose molecules can form strong hydrogen bonds with the solvent (water) molecules, so glucose is soluble in water.
Detailed explanation-3: -Glucose contains five hydroxyl groups (−OH). Therefore, glucose is involved in intermolecular hydrogen bonding with water molecules, so it is readily soluble in water.
