1. A Review of General Chemistry

Benzyl bromide is a primary halide. It undergoes S_N1 substitution about as fast as most tertiary halides. Use resonance structures to explain this enhanced reactivity.

For each of these ions, draw the important resonance forms and predict which resonance form is likely to be the major contributor.

(c)

For each pair of ions, determine which ion is more stable. Use resonance forms to explain your answers.

(e)

(f)

In the following sets of resonance forms, label the major and minor contributors and state which structures would be of equal energy. Add any missing important resonance forms.

(d)

(e)

Use resonance structures to identify the areas of high and low electron density in the following compounds:

(a)

(b)
