- Why does the triple bonded carbon in C2H3N get counted three times towards the molar mass, but the triple bonded nitrogen only gets counted once? Why doesn't the nitrogen get counted three times as well?Wednesday 5:40 PM 3 of 160 Examine the given molecule below and choose the wrong answer about it; di OH Lütfen birini seçin: a. Dehydration of this molecule can give two different products b. It can form intermolecular hydrogen bonds c. Since it is totally aromatic it cannot give dehydration reactions d. It has a chiral center e. The chromic acid test result of this molecule is positiveIf exactly 3 moles of propanol (C3H8O) is combusted in the presence of excess oxygen (O2) for form carbon dioxide (CO2) and water (H2O), how many moles of water will be produced? Enter the integer number of moles of H2O, do not enter the unit. Hint: Since this problem and two problems below rely on this reaction, make sure you balance this reaction very carefully on paper as your first step before doing any calculations. The reaction to be balanced is reaction between C3H8O(l) and O2(g) to produce CO2(g) and H2O(l).
