Note: you can select a structure and use Copy and Paste to save drawing time. CHarrow_forwardDraw the product of syn addition of Br2 across the double bond of the alkene in the drawing area below. Important! Be sure you use dash and wedge bonds to show the stereochemistry at any new chiral centers in the product. Note for advanced students: if the product exists as a pair of enantiomers, just draw either one of them. Х 5 Br.

- Methyl isocyanate, CH3 -N= C = O, is used in the industrial synthesis of a type of pesticide and herbicide known as a carbamate. As a historical note, an industrial accident in Bhopal, India, in 1984 resulted in leakage of an unknown quantity of this chemical into the air. An estimated 200,000 people were exposed to its vapors, and over 2000 of these people died. Q.) Methyl isocyanate reacts with strong acids, such as sulfuric acid, to form a cation. Will this molecule undergo protonation more readily on its oxygen or nitrogen atom?

H,N но PE PC In order to synthesize PC from PE, PE is reacted with three S-adenosylmethionine (SAM) molecules, producing three S-adenosylhomoserines (SAH). Draw the chemical reactions leading from PE to PC, including the important intermediates. Use the arrow formalism. Feel free to abbreviate certain groups with R to avoid excessive drawing, but make sure to draw the full substrates and products with all atoms at least once.
