6236 days or 17 years and 27 days between the examination of inorganic chemistry and organic chemistry to. This provision may be approved at the Guinness Book of Records?

[UPDATE] I also added some answers to the questions "strange". The questions of my organic chemistry exam, for future reference:

  • hybridization sp 3 / sp 2 / sp.
    • This is a classic response. Studying the hybridizations
  • Write all the numbers of oxidation of carbon and for each number, write a compound with this number of oxidation
    • The carbon can take all the oxidation numbers between -4 and +4. Methane (-4), methyl group (-3), ethene (-2), ethyne (-1), formaldehyde (0), aldehyde non-formaldehyde (+1), ketone (+2), carboxylic acid (+3) Carbon dioxide (+4)
  • all the compounds I know that form the cabossile and which are formed from the carboxyl including the Cannizzaro reaction
    • A book of organic chemistry can help
  • What's so special about anhydrides?
    • anhydrides have special that the binding carboxyl-OO-carboxyl is a bond highly energy thanks to the presence, on both sides, precisely the bond carboxyl which tends to suck a bit 'the electrons of the links-OO-thus making this a bond little 'more' hard to break and therefore more 'energy many that a similar link with P instead of C is used as the molecule of choice for the transport of energy in our body, the ATP
  • 'Cause the link is better than an anhydride carbonyl-alcohol
    • anhydride bond and 'better than cabonile-alcohol because the other side (the side alcohol) there is no' a carbonyl group which, in fact, make the important link with the great energy contained within it. Since the carbonyl is only one part, and this bond 'little energy. I hope I explained myself.
  • Where do you want to go carbon
    • This seems very strange out of context. In reality, the question came out when I was writing the compounds of carbon with an oxidation number of +4. I had already written the above as an example CO 2 carbon at +4 but then I had better do it all and remade this oxidation number I had written, in second place on CCl 4 and he says to me "and then" and I am writing CBr 4, and he "then", and I write the CI 4 and he "then" and I write the CF 4 and him "and then" I'm stuck at this point and he asked that question of where he wants to go carbon. Took me a few seconds to realize that she wanted the CO2.
  • Write the ATP and to explain the differences between the three-OPO-linkages
    • The first two are high-energy bonds because "encapsulated" between two carboxyl groups. The last is located between a carboxyl and an alcohol on the ribose and thus does not have all this energy as the first two.
