Look at the given spectroscopy data. How many degrees of unsaturation are present in this molecule? The IR at 1735 cm-1 is indicative of a type bond and when combined with the 13C NMR signal at 172 ppm and general H NMR is indicative of a(n) functional group. The 1HNMR peak at 6.3 ppm and broad signal at 3325 cm-1 in the IR is indicative of a(n) that is bonded to a

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
