Question

A compound containing carbon, hydrogen, and perhaps other elements shows a mass spectrum with a molecular ion at 115. Suggest at least 2 possible structures for the compound.

In the molecular ion region of the mass spectrum, a compound containing carbon, hydrogen, and perhaps other elements gives peaks at 90 and 92. The 92 peak is about 1/3 the height of the 90 peak. Give at least 2 possible structures for the compound.

Answer 1

Answer] # Compound contain carbon and hydrogen and other element # Molecular ion at miz = 115 show Compound have a molecular weight 115 # The odd mous of molecular ions indicate compound have have odd number of nitrogen, according to 'Nitrogen rule? # Possible poolecular kormula - According to rule o$13 172 = n=8, 8=11 entintre estig 115 13 Consider compound have one nitrogen atom, then remove chia Istom kormula o cale of 13.
