) Anion and alkoxy (RO
). Which of the following statements is correct? (1) RS
is less basic but more nucleophilic than RO
. (2) RS
is more basic and more nucleophilic than RO
. (3) RS
is more basic but less nucleophilic than RO
. (4) RS
is less basic and less nucleophilic than RO
.
Ans.
(3)
Sol.
RS
is more nucleophilic than R
-
O
due to larger size of orbitals and polarization but RS
is less basic thanR
-
O
as the negative charge get stabilized due to larger size of sulfur atom.
