WebThe carbon-13 (13C) NMR spectrum of compound A,C8H8O2, contains six peaks. Compound A reacts with an excess of bromine water to give compound B,C8H6Br2O2. Compound A reacts with alkaline aqueous iodine to form a yellow precipitate C and compound D. Compound D reacts with PCl5 to form compound E,C7H5O2Cl. WebThe isotope carbon-12 (12 C) forms 98.93% of the carbon on Earth, while carbon-13 (13 C) forms the remaining 1.07%. The concentration of 12 C is further increased in biological materials because biochemical reactions discriminate against 13 C.
