Tardigrade Admin · Accepted Answer

N 2 H 5+is formed from N 2 H 4 which has a lone pair of electrons on 'N' and positive charge on 'H' takes away its electron and to complete duplet, a co-ordinate bond is present from N to H. H 4 N 2+ H + arrow[ H 4 N 2 arrow H ]+

Q. Which of the following contains a coordinate covalent bond ?

$N_{2} H_{5}^{+}$

$B a C I_{2}$

$H Cl$

$H_{2} O$

$N_{2} H_{5}^{+}$ is formed from $N_{2} H_{4}$ which has a lone pair of electrons on ' $N$ ' and positive charge on ' $H$ ' takes away its electron and to complete duplet, a co-ordinate bond is present from $N$ to $H$ .
$H_{4} N_{2} + H^{+} \to [H_{4} N_{2} \to H]^{+}$
