To determine which of the given compounds is expected to be optically active, we need to identify if any of the compounds have a chiral center. A compound is optically active if it can rotate plane-polarized light, which is typically due to the presen
One is a mirror-like structure at the base of the eye, which reflects the light across the photoreceptors for a second time. The structure of the compound eye also allows each facet to supplement the light that strikes it with light from as many as 600 others. Kelber suspects that many ...
An element is a substance that is made up of one type of atoms which means that these atoms have the same proton number. When two or more elements combine, a compound is formed. Upon combination, the elements lose most of their individual physical and chemical properties....
