Consider thiol anion (RS⊖)\left( {R{S^ \ominus }} \right) and alkoxy anion(RS⊖)\left( {R{S^ \ominus }} \right). Which of the following statement is correct?
View answer and explanation
Correct option: B
RS⊖R{S^ \ominus } is less basic but more nucleophilic than RO ⊖R{O^{\, \ominus }}
Option B (CH3−C.H−CH3<(CH3)2C.−CH2−CH3<(CH3)3C.C{H_3} - \mathop C\limits^. H - C{H_3} < {\left( {C{H_3}} \right)_2}\mathop C\limits^. - C{H_2} - C{H_3} < {\left( {C{H_3}} \right)_3}\mathop C\limits^.) is correct because the stability of free radicals increases with increasing substitution due to hyperconjugation and inductive effects.
