Explain why \(\mathrm{SO}_{2}\) is used as a reducing agent but \(\mathrm{SO}_{3}\) is not.

Text Transcription:

SO_2

SO_3

Step-by-Step Solution:
Step 1 of 3

Classnotes – Rivera – Sn1 and Sn2 reactions A nucleophile is an electron rich species that will react with an electron poor species. A substitution implies that one group replaces another. There are 2 fundamental steps to these reactions: - Formation of the new bond to the nucleophile - Breaking of the bond to the leaving group. Sn2 reaction characteristics  “Substitution, Nucleophilic, Bimolecular reaction”  This pathway is a concerted mechanism (single step), where there is a simultaneous attack of the nucleophile and displacement of the leaving group.  The effect of the leaving group: o Reactivity order: RI > RBr > RCl > RF o The weaker the basicity, the stronger the leaving group o Larger atoms are more polarizable…Same size Look at the strength of base/nucleophile, the stronger the nucleophile the faster the reaction.  NH 2 OH > F- -  The effect of the alkyl group (# of carbons): o Reactivity order: primary > secondary > tertiary > quaternary  The effect of the solvent: o Polar Aprotic Solvent: has dipole moment but no hydrogen binding  Nucleophile strength in Polar Aprotic solvents: - - - - o F > Cl > Br > I o A negatively charged nucleophile is always stronger than its conjugate acid  The effect of the nucleophile: o more reactive nucleophiles will be favored bc they are involved in the rate
