During normal grain growth, grain boundaries tend to move toward the center of curvature so that small grains get smaller at the expense of larger grains. During recrystallization, however, the opposite is true. Explain why this is.
Draw the structure of the following three isomeric amides with chemical formula C6H11NO. Draw all three structures in the same window, DO NOT separate them with an arrow
Activating effects: Using resonance contributors, explain why the methoxy group is an activator and an ortho/para director in electrophilic aromatic substitution A drawing would be helpful too
