If HCO₃ That is radioactively labeled with ¹³C is available,which carbon atom in the molecule below would ultimately be expected to be radioactive? A) A B) B C) C D) D

Quizplus · Accepted Answer

The radioactively labeled molecule HCO₃ 11ea8d43_abb1_e87b_b445_bbf7a2830b95_TB6697_11_TB6697_11 contains an ¹³C group. This group can substitute the carbon atom to which it is attached by an SN2 reaction with the nucleophile of the molecule it encounters. In the molecule given, the only carbon atom that has a nucleophilic atom (i.e., a nitrogen atom) attached to it is the carbon atom C. Therefore, C is the best choice for a carbon atom that would ultimately be expected to be radioactively labeled.
