Look carefully at the frontier MOs of the diatomic molecule, BF and determine the most basic site. Based on your observations, predict the structure that results when H+ adds to BF. For your answer, draw the product as a Lewis structure that satisfies the octet rule for both boron and fluorine.
The mass spectrum of an organic compound shows the relative abundances of M to be 62.87% and M 1 to be 4.760%. Assuming the peaks are caused by 12C and 13C isotopes,
