Question

Which of the following is not correct?

$OrderofbasicityOrderofnucleophilicity\left(a\right)F^{-}>C{l}^{-}>B{r}^{-}B{r}_{-}>C{l}^{-}>F^{-}\left(b\right)H-O-O^{-}>O{H}^{-}H-O-O^{-}>O{H}^{-}\left(c\right)C{H}_3>N{H}_2^{-}>OH-C{H}_3>N{H}_2^{-}>O{H}^{-}\left(d\right)H_{2}O>H_{2}S{H}_{2}O<H_{2}S$

• A. $F^{-}>C{l}^{-}>B{r}^{-}B{r}_{-}>C{l}^{-}>F^{-}$
• B. $H-O-O^{-}>O{H}^{-}H-O-O^{-}>O{H}^{-}$
  
• C. $C{H}_3>N{H}_2^{-}>OH-C{H}_3>N{H}_2^{-}>O{H}^{-}$
  
• D. $H_{2}O>H_{2}S{H}_{2}O<H_{2}S$
  

Answer 1

The correct option is B

$H-O-O^{-}>O{H}^{-}H-O-O^{-}>O{H}^{-}$

Peroxide ion is more nucleophilic but less basic than $O{H}^{-}.$
