Draw the anionic intermediate thatforms after sodium hydride reacts and the final organic product.Hints: what type of nucleophile is NaH and where does that mean it will react?

Br Brz CH3 CH3 H3C CH2CI2 H3C Br Electrophilic addition of bromine, Br2; to alkenes yields a 1,2-dibromoalkane. The reaction proceeds through a cyclic intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH,Cl). In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion to yield the product. Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ion so that a product with anti stereochemistry is formed.

4. A CHEM 245 student wants to synthesize some ethylene glycol to use as antifreeze in his radiator this winter. He proposes the following reaction to his instructor, who quickly explains that this reaction won't work as proposed due to the student's choice of reagent. 1) NaH 2) H20 OH Но a) Why can't sodium hydride (NaH) be used as the nucleophile in the reaction above? b) Propose an alternate reagent that COULD be used with the ethylene oxide to successfully give the desired ethylene glycol product.
OH NaOH Halobenzenes that do not have electron-withdrawing groups can still undergo substitution under conditions of high ter pressure. The reaction proceeds via a triple-bond intermediate called benzyne, Normal triple bonds arise from the over p orbitals to form two pi bonds. In benzyne, the first pi bond is formed normally, but the second is formed via weak o orbitals. Draw curved arrows to show the movement of electrons in this step of the mechanism.
