Chemistry: A Molecular Approach 3
Amino acids are the building blocks of proteins. The simplest amino acid is glycine (H2NCH2COOH). Draw a Lewis structure for glycine. (Hint: the central atoms in the skeletal structure are nitrogen bonded to carbon, which is bonded to another carbon. The two oxygen atoms are bonded directly to the ri

Despite many attempts, the perbromate ion (BrO4 2) was not prepared in the laboratory until about 1970. (In fact, articles were published explaining theoretically why it could never be prepared!) Draw a Lewis structure for BrO4 2 in which all atoms have lowest formal charges.

Write a mechanism for each of the following reactions: a. the uncatalyzed hydrolysis of methyl propionate. b. the aminolysis of phenyl formate, using methylamine.

Sensation and Perception 10
Texture gradients are said to provide information for depth perception because elements in a scene become more densely packed as distance increases. The examples of texture gradients in Figures 10.6 and 10.8 contain regularly spaced elements that extend over large distances. But regularly spaced elem
