Which is the liquid having lowest rate of evaporation?

The liquid with the lowest rate of evaporation is typically water at standard conditions due to its strong hydrogen bonding. Among common liquids, substances like glycerol or certain oils (e.g., silicone oil) also exhibit low evaporation rates, largely due to their high molecular weight and strong intermolecular forces. These factors contribute to their ability to retain molecules at the surface, thereby reducing the rate of evaporation.
