B The reaction must be concerted for a trans product to be formed. (C) Br must add first as an electrophile and then bromide must add second as a nucleophile. D Bromide must add first as a nucleophile and then Br must add second as an electrophile.

Draw the alkene structure that produced the following compounds in a ozonolysis reaction as specified. 1. O3 2. (CH3)2S You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. In cases where there is more than one answer, just draw one.

Paragraph 10. Answer ALL parts of this question. Treatment of acetylcyclopentane (see Scheme Q10a) with NaOEt in ethanol at 25 °C results in formation of a major, thermodynamic enolate (Scheme Q10a). NaOEt Thermodynamic enolate ELOH 25 °C (Scheme Q10a) (a) Draw the structure of the thermodynamic enolate. (b) Explain why the enolate in answer (a) is the major enolate present in the equilibrium at room temperature. (C) Draw the product formed when the thermodynamic enolate (1 mole) reacts with ethyl acrylate (1 mole) (Scheme Q10c). OEt + NaOEt Thermodynamic enolate Product ETOH 25 °C C12H2003 (Scheme Q10c) (d) Draw the kinetic product formed when 1-cyclopentene-1-carbaldehyde reacts with sodium cyanide at low temperature (5 °C) and over a short reaction time (5 minutes) (Scheme Q10d). NACN Kinetic product ELOH 5 °C (Scheme Q10d) >
