Packet 7: Tossup 15

Electrons from a filled d orbital in a coordination compound donate into a vacant one of these interactions in backbonding. (15[4])One type of these (15[1])interactions (-5[1])act as a nucleophile in the first step (15[1])of oxymercuration (-5[1])demercuration. (-5[1])Huckel’s rule (-5[1])determines (-5[1])aromaticity (-5[1])based on the number (15[1])of electrons belonging (15[1])to these (15[1])interactions. (15[5]-5[1])Conjugated systems (-5[1])possess a delocalized (15[1])network of these (15[1]-5[1])interactions. (15[2]-5[2])(*) Sp2 hybridization permits (10[1])the formation of these interactions (10[1])that form (10[1])from the sideways overlap of p orbitals. (10[1]-5[1])A double bond (10[1])contains a sigma bond and, for 10 (10[1])points, (10[3])which (10[1])other (10[1])type of bond? (10[3]-5[1])■END■ (10[9]0[3])
