Explain how alkene/aromatic C-H stretches are distinguished from alkane C-H stretches. Do the C-H stretch peaks in the IR spectra of triphenylmethanol, bromobenzene and benzophenone occur in the expected alkene/aromatic C-H stretching region?
two naturally occurring isotopes, Re-185 (mass = 184.935 amu) and Re-187 (mass = 186.956 amu). Calculate the percent abundances of the isotopes of rhenium.
Grignard reagents (RMgX) are extremely strong bases and nucleophiles. Comlete the following reactions which demonstrate these two properties.
