You were tasked to propose a structure for a compound with a chemical formula of C7H₂N. In the laboratory, the compound appears as a clear, colorless liquid. To determine the structure of the compound, you subject the compound to several solubility tests and chemical tests. The observations for these tests are summarized: SOLUBILITY GROUP: Group V Insoluble in water and 10% NaOH but soluble in 10% HCI FUNCTIONAL GROUP/CLASS: Amine 1) Based on the results of the solubility tests and chemical tests, what is the most probable structure of C,H,N? Draw your answer in the box below. You may draw the compound using line-bond formula OR Lewis structure. |

The amines are organic weak bases which are nitrogen-containing. In the early days of organic chemistry, basic amines derived from natural sources were known as “vegetable alkali”, but they are now referred to as alkaloids. The study of alkaloids provided much of the growth of organic chemistry, phytochemistry and natural products chemistry. It remains a fascinating area of research. Please search for one naturally occurring alkaloid and provide the following: Name of the alkaloid and show its structure. Identify using arrows the polar bonds in the structure Species from where it was isolated What was the use of this alkaloid in plants (if any)? What are the pharmacological, medicinal, or environmental uses or applications of this alkaloid (if any)?
Amines as Bases. Explain ?
a) HCl solubility test One common organic functional group, the amine group, is found in compounds that are insoluble in water but soluble in aqueous HCl solution. Draw the structure of a compound with this functional group. Write the equation for the reaction of this compound with aqueous HCl solution. Explain why amines would be soluble in aqueous HCl even though they are insoluble in water. The compound should have 15 number of carbons. b) Bromine test for alkenes Draw the structure for an alkene, then write the mechanism (using electron pushing arrows) and predict the product for the reaction between this alkene and Br2. Bromine is orange color, and bromoalkanes are colorless. Explain what the reactants and products would look like before and after this reaction occurs. The compound should have 15 number of carbons.
