These questions is based on Grignard Synthesis of Malachite Green A) During the final quench..which you will do with the SLOW addition of 5% HCl...you probably will note the evolution of a gas. What is the identity of the gas and how was it formed (show the reaction)? B) Notice that the malachite green is actually a quaternary ammonium salt. The organic portion is shown in brackets with a + charge overall. According to the structure shown, where (on what atom) does the formal +1 charge likely 'reside' and why? C) Notice that we are using THF (tetrahydrofuran) instead of diethyl ether as the solvent here. Hmmm....it's more expensive and harder to keep dry. Nonetheless, there is a very simple, practical reason why THF was necessary here. Check out the structure and pertinent physical properties of THF versus diethyl ether. What necessitated the use of THF?
