A) Deduce the structure of compound A. Draw all non-bonding electrons (as applicable) (b) Give a curved-arrow mechanism for the conversion of A into 3,6-dimethylphthalic anhydride. The catalyst H2SO4 is abbreviated as \"H–B\" below and its conjugate base is abbreviated as \":B–\". Follow the directions above each drawing box. First step: Delete/Add bonds to form A, Second step: Draw missing bond and Add 2 curved arrows to give next product. curved arrow.

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced. be sure your answer has the correct number of significant digits.
