The band gaps among conductors, insulators, and semiconductors are to be explained. Concept introduction: Semiconductors are the solids that have a conductivity between those of conductors and insulators. In a semiconductor, the gap between the conduction band and the valence band is small, so the electrons may jump from valence band to conduction band. Conduction band: The conduction band is the band of electron orbitals that electrons can jump up into from the valence band when excited. Valence band: The valence band is the band of electron orbitals that electrons can jump out of, moving into the conduction band when excited. A Dopant, also called a doping agent, is a trace impurity element that is inserted into a substance (in very low concentrations) to alter the electrical or optical properties of the substance. Doping: Addition of dopant is doping. n-Type semiconductor: A semiconductor that has been doped with electron donor atoms is called an n-type semiconductor. p-Type semiconductor: A semiconductor that has been doped with electron acceptor atoms is called a p-type semiconductor.

Interpretation Introduction

Interpretation:

The band gaps among conductors, insulators, and semiconductors are to be explained.

Concept introduction:

Semiconductors are the solids that have a conductivity between those of conductors and insulators.

In a semiconductor, the gap between the conduction band and the valence band is small, so the electrons may jump from valence band to conduction band.

Conduction band: The conduction band is the band of electron orbitals that electrons can jump up into from the valence band when excited.

Valence band: The valence band is the band of electron orbitals that electrons can jump out of, moving into the conduction band when excited.

A Dopant, also called a doping agent, is a trace impurity element that is inserted into a substance (in very low concentrations) to alter the electrical or optical properties of the substance.

Doping: Addition of dopant is doping.

n-Type semiconductor: A semiconductor that has been doped with electron donor atoms is called an n-type semiconductor.

p-Type semiconductor: A semiconductor that has been doped with electron acceptor atoms is called a p-type semiconductor.

5. Propose a Synthesis for the molecule below. You may use any starting materials containing 6 carbons or less (reagents that aren't incorporated into the final molecule such as PhзP do not count towards this total, and the starting material can have whatever non-carbon functional groups you want), and any of the reactions you have learned so far in organic chemistry I, II, and III. Your final answer should show each step separately, with intermediates and conditions clearly drawn. H3C CH3
