Question

what will be name of R3Co- anion or RC(R')(R'')O- anion

Answer 1

Answer:

Nucleophilic strength depends on the electronegativity of the atom. Lower the electronegativity of an atom, larger the nucleophilic strengih of an aiom and more readily ii will donate electrons to the eleotrophilic (e- deficient) species.

Since, electronegativity decreases down the group, thus nucleophilic strength increases down the group, Hence, RS- is more nucleophilic than RO- due to less elecironegativity oi S than O.

On the other hand, basic strength of an atom depends upon the tendency to accept a proton more readily. Since, O-H bond is longer than S-H bond, thus, RO- has a greater tendency to accept a proton than RS-. Hence, ,RO- is a stronger base than RS-. Thus, basic strength oi the central atom decreases down the group.

Hence, RS- is more nucleophilic but less basic than RO-
