Acetone is highly soluble in water but benzophenone is not. Give reasons. |
| Answer» Solution :In acetone, C=O group easily forms H-bonds with water and hence acetone is highly soluble in water. HOWEVER, in benzophenone, the phenyl GROUPS are BULKY and hence C=O groups cannot form H-bonds with water due to st ERIC hindrance and hence benzophenone is INSOLUBLE in water. | |
