1. Which is less soluble in water, 1-pentanol or 1-heptanol? Explain. 2. Write an equation for the reaction of methanol with sodium 3. Write an equation for the reaction of 2-butanol with the Lucas reagent. 4. Describe the odor of the product derived from mixing isopentyl alcohol and acetic acid, and write the equation for its formation Solution 1) 1-heptanol is lest soluble in water. Because solubility depend upon the type of bond present in the molecule.1- heptanol has loneger non polar chain as compare to 1- heptanol. Hence its hydrophobic part make it less soluble in water.Therefore from above conclusion we an say that 1- heptanol is less soluble in water as comare to 1- pentanol..
