Calculate the degree of unsaturation in the following formulas and draw a possible structure for each C8H8O C4H7Cl
Give equations to show how sulfuric acid can convert 4-methyl cyclohexene into a mixture of four isomeric c7H12 compounds(including starting material). Predict the relative amounts of each isomer.
15.0 mL of 0.50 M HCl is added to a 100.-mL sample of 0.496 M HNO2 (Ka for HNO2 = 4.0 × 10-4). What is the equilibrium concentration of NO2- ions?
At 63.5C the vapor pressure ofH2O is 175 torr, and that of ethanol,C2H5OH, is 400 torr. A solution is madeby mixing equal masses of H2O andC2H5OH.
