Electrical properties in metals, insulators and semiconductors should be explained with reference to the concept of chemical bonding. Concept introduction: Chemical bonds are essentially forces of attraction between atoms (molecules or ions) that hold the solid together. Bonding in solids can be explained based on band diagram, which is an electron energy level diagram that employs the concept of valence and conduction bands Solids can be classified as metals, semiconductors and insulators based the gap or the energetic distance between the valence and conduction bands Electrical properties of solids arise due to the movement of electrons in the conduction bands.

Hi!! Please provide a solution that is handwritten. Ensure all figures, reaction mechanisms (with arrows and lone pairs please!!), and structures are clearly drawn to illustrate the synthesis of the product as per the standards of a third year organic chemistry course. ****the solution must include all steps, mechanisms, and intermediate structures as required. Please hand-draw the mechanisms and structures to support your explanation. Don’t give me AI-generated diagrams or text-based explanations, no wordy explanations on how to draw the structures I need help with the exact mechanism hand drawn by you!!! I am reposting this—ensure all parts of the question are straightforward and clear or please let another expert handle it thanks!!
