Which of the following species is not electrophilic in nature?
Which of the following species is not electrophilic in nature?
$\stackrel{\oplus}{\mathrm{Cl}}$
$\mathrm{BH}_3$
$\mathrm{H}_3 \stackrel{\oplus}{\mathrm{O}}$
$\stackrel{\oplus}{\mathrm{N}} \mathrm{O}_2$
Solution
Electrophiles are electron deficient species. Among the given, $\mathrm{H}_3 \mathrm{O}^{\oplus}$ has lone pair of electrons for donation, thus it is not electron deficient and hence, does not behave like an electrophile.
