Exercise $$\PageIndex{1}$$

Determine which enolate will form and label it as the kinetic or thermodynamic enolate.  This is the thermodynamic enolate. Higher temperatures and reversible conditions lead to the more stable enolate.

Exercise $$\PageIndex{2}$$

Determine which enolate will form and label it as the kinetic or thermodynamic enolate.  This is the kinetic enolate. Lower temperatures and strong hindered bases lead to the less substituted enolate.

Exercise $$\PageIndex{3}$$

Draw a reasonable mechanism for formation of the enolate, followed by reaction with bromoethane  Exercise $$\PageIndex{4}$$

Draw a reasonable mechanism for formation of the enolate, followed by reaction with bromoethane  Exercise $$\PageIndex{5}$$

Write out a reasonable synthesis for the following transformation
