Question

The total number of electrophiles present in the following set is/are_____.
$SnC{l}_4,ZnC{l}_2,N{O}_2^{+},H_3{O}^{+},N{H}_4^{+},N{F}_3,H_{2}S,$ $C{H}_2=CH-C\equiv CH$

Answer 1

Answer: 4

Charged electrophile: $N{O}_2^{+}$
Neutral electrophiles: $SnC{l}_4,ZnC{l}_2,N{F}_3$ .
$H_3{O}^{+},N{H}_4^{+}$ cannot act as electrophiles since they already have an octet of electrons in their respective valence shells. Hence, they cannot accept a pair of electrons.
Nucleophiles: $H_{2}S,C{H}_2=CH-C\equiv CH$ .
