The reason of solubility of thymol in 1.0 M NaOH whereas its slightly soluble in water needs to be explained. Concept Introduction: Organic compounds are mainly composed of C and H atoms. It is the branch of chemistry that deals with preparation, reactions, and properties of organic compounds. The atom or group of atoms which are responsible for all special chemical and physical properties of a substance is called as a functional group . These groups are bonded to the parent carbon chain of the organic molecule. Organic compounds are mainly covalent compounds in which C-C, C-H and C-X bonds are present. Here 'X' indicates heteroatom which is present in functional group. The C-C and C-H bonds are non-polar covalent bonds as the difference between the electronegativity of C and H is very less. On the contrary the polarity of C-X bond depends on the electronegativity of X. If X is O, N or halogen, the C-X bond will be a polar covalent bond that makes the polar organic molecule.

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ? Will the first MgBr product that forms in this reaction create a new CC bond? olo ? OH جمله O Yes Ⓒ No MgCl ? Will the first product that forms in this reaction create a new CC bond?
