I do not know how to begin this question. how do you identify the location of missing double or triple bonds. what

Your UANet ID: _____________________ Chemical Thinking U2 M3: Discussion 8 Drug StructureNorepinephrine is a neurotransmitter in our body. The ball-and-stickrepresentation of a molecule of this substance is shown in the image.1. Identify the location of missing double or triple bonds in thisrepresentation.2. Identify the different functional groups in this molecule. 3. Draw the Lewis structure of this moleculeand label the molecular geometries of thevarious atomic centers in this molecule Guaifenesin is a component of some over-the-counter drugs usedas expectorants. The skeletal or line structure of a guaifenesinmolecule is shown in the image4. Identify the different functional groups in this molecule; 5. Describe the different molecular geometries around 4 different central atoms in this molecule; 6. Estimate the value of the selected bond angles. Consider the line structure of Nicotine:7. Identify the location of the missing hydrogens and predict the value ofthe s elected bond angles. | 2
