An acyl halide reacts with a primary amine to form what molecule?
A primary amine reacts with an acyl halide to form an amide. The chorine group on the acyl halide is a fantastic leaving group which makes it susceptible to a nucleophile attack. Therefore, the nitrogen on the primary amine group can attack the carbonyl carbon and successful form an amide.
General Chemistry Question: Which of the following is amphoteric? A) NO2- B) HSO3- C)CN- D)NH4+ E) (PO4)3-
B. The first step is to determine what amphoretic means. Amphoretic is a molecule that can act as an acid or a base. In other words, it can accept and donate H+ ions. Knowing this one can eliminate A, C, and E because they do not have any H+ ions to donate! Between B and D, D's Nitrogen already has a full octet and can no longer accept any H+ ions. Therefore, the answer is B because it can donate its H+ ion but the sulfur atom can also accept another H+ ion since its octet is not full.
An increase in blood glucose concentration results in all of the following EXCEPT: A) Decrease in insulin production B) Increased urine concentration C) Increased parasympathetic activity D) None of the above will occur
A. As blood glucose concentration increases insulin is need to cause glucose to move into cells and out of the blood. Urine would increase in concentration to remove excess sugar and the parasympathetic system's activity would increase to promote digestion.
