Draw the structure of the product formed in the reaction of an epoxide with ethoxide ion. If more than one stereochemical product is possible, draw only one isomer. The starting material is a 6 carbon ring fused to an epoxide through carbons 1 and 2. Both carbons have a wedged bond to the epoxide oxygen and a dashed bond to hydrogen. Step 1 reacts with sodium ethoxide, C H 3 CH 2 O minus. Step 2 is H plus and ethanol. Clearly indicate stereochemistry by drawing a wedged bond, a dashed bond and two in‑plane bonds per chiral carbon. The product(s) of the reaction are characterized as being achiral. S, S. racemic. R, S. S. R, R. R.

Ase your answer to this question on the information below. hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant. the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen. chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product. nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.
