Light bulbs transform electrical energy to light energy. No energy transformation is 100%. Thus, in the transfer from electrical

energy to light energy, some energy is dissipated as heat. The efficiency of an electrical device depends on: 1. how much energy is wasted ‐ transferred to unwanted stores 2. how much energy is transferred to useful stores The more energy a device wastes, the less efficient it is. The graph shows the efficiency of three types of light bulbs: incandescent, fluorescent, and LED. What can you conclude about the energy efficiency of the light bulbs? A) Incandescent light bulbs use less energy than either LED or fluorescent bulbs. B) Fluorescent light bulbs are the most energy efficient since their light and heat energy are most equal. C) Incandescent light bulbs rely on heat energy to process light, increasing the light output while decreasing the heat output. D) LED light bulbs provide more light energy while producing less heat energy, making them the most energy efficient of the three types of bulbs.

D( )-Camphor is treated with 5-methoxytryptamine in the presence of sodium cyanoborohydride to generate a new molecule, as a sin
Svetach [21]

The reducing agent can approach the carbonyl face of camphor by forming a one carbon bridge (known as an exo attack) or a two carbon bridge (termed endo).

The two resultant stereoisomers are known as isoborneol and borneol (from exo attack) (from endo attack). Gas chromatography (GC) analysis may be used to calculate the ratio of each isomeric alcohol in the mixture. Unfortunately, IR analysis does not permit this.

The stereochemistry of the reaction is regulated in stiff cyclic compounds like camphor and norcamphor by protecting one side of the carbonyl group from the reagent's assault. The hydrogen atom is added to the endo side, creating the exo alcohol isoborneol, while the methyl groups on the one-carbon bridge of camphor screen the approach of the hydride from the "top" or exo side of the two-carbon bridge. You will be asked to guess the main isomeric alcohol created by the norcamphor hydride reduction later in the lab report.
