How do you know when to draw a solid wedge vs a dashed wedge when drawing 3D bond-line structures? I know that solid-wedge means the atom is pointing towards you and dashed wedge means it's in the back, but how do you know which atoms are in the front as opposed to the back? How can you tell what the configuration will look like in space just by looking at the lewis structure or name?
1.- Answer the following questions: (a) What is electronegativity? (b) How is electronegativity measured numerically? Name the scale used and the range of values in the scale. (c) Explain how electronegativity differences between atoms result in nonpolar covalent bonds and polar covalent bonds. Make sure you explain the difference between nonpolar covalent and polar covalent bonds as it relates to the electronegativity of the participating atoms.
