Chemistry - GOC Question with Solution | TestHub

All neutral groups listed are -I in the usual classification, while -O⁻ is +I, giving x=10. The printed ratio 3.33 implies y=3. Sulfinyl group (6) can switch from resonance donor to acceptor with the conjugated partner. Standard electronic-effect lists classify (8) -OCOR and (9) -NHCOR as +R when attached through O or N; an internal carbonyl alone does not prove -R toward the parent. The source supplies no parent conjugated structure or conditions for its both-effect count. Printed 3.33 is preserved, but y=3 is not uniquely proved from these isolated groups. The intended convention needs clarification before scored use.
