Please answer both
Is the product of this reaction more or less soluble than the initial molecule? Why? 1. RCO;H 2. H*, H,O Less water-soluble More water-soluble Water-solubility improved due to a negative charge on the product. Water-solubility improved due to a positive charge on the product. The product now has sufficient H-bonding functional groups to support water-solubility. An acetal has been formed which would decrease the water-solubility Another reason
