1.	Among the following, the best and the least `H^(Θ)` ion donor, respectively, are:A. B. C. D.
Answer» Correct Answer - A::C The `bar e`-donating order of (OMe) group: `{:(P-OMe,gt,o-OMe,gt,m-OMe),((I),,(II),,(III)),((underset("net more ED")("+R and -I,")),,(underset("so net less ED than (I)")underset("at orarr-I at p")("+R and -I but -I")),,(underset("net EW")underset("at meta")(Only -I))):}` Decreasing order of `overset(Θ)H` donor: `underset(("Best"))(a)gt(b)gt(d) underset(("Least"))("standard")gt(c )`
