Incorrect Question 4 0/1 pts Determine the correct order of steps that will occur for the possible reaction shown below. To enter your answer, use the numbers that are adjacent to the correct descriptions in the correct order. For example, if you felt that 1, followed by 2 and then 3 reflects the correct ordering of reaction steps, then you would enter: 1, 2, 3 for your answer. Do so even if the reaction sequence includes two distinct...

Incorrect Question 9 0/1 pts Choose the correct statement concerning electric field lines: At any point, the electric field lines are vectors in the direction of the electric field None of these answers are correct. At any point, the electric field is parallel to the tangent to a curved field line at that point Electric field lines are trajectories of a test charge. Electric field lines point away from negative charge.

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
