Question

Which of the following species is not electrophilic in nature ?

• A. $\ce{ BH_3}$
• B. $H_3\overset {\oplus}O$
• C. $\overset{\oplus}N O_2$
• D. $\overset{\oplus}C l$

Answer 1

Answer: (B)

$H_3\overset {\oplus}O$

Answer 2

Electrophones are electron deficient species. Among the given, ${H_3O^{\oplus}}$has lone pair of electrons for donation, thus it is not electron deficient and hence, does not behave like an electrophone.
