write the two resonance hybrids for the carbocation that would be formed by protonation at C-1 of 2-methyl-1,3-pentadiene. Without doing a calculation, would you expect C-2 or C-4 (the two end carbons of the allylic cation) to have the most positive charge on it?
How many grams of CaH2 (Molar Mass = 42.1 g/mol)are needed to generate 10.0 L of H2 gas if the pressure of H2 is 769 torr at 28.0°C?
calculate the pH formed by mixing 100 mL of 0.20 M HCL with 50 mL of 0.30 M NaOH.
Using a single reagent and only reaction chemistry that was part of this experiemnt, how could you distinguish between the following pair of substances contained in seperate test tubes?
