$NH_4^+$

Vedclass · Answer

(B) The correct answer is $(B)$.In the ammonium ion $(NH_4^+)$,the nitrogen atom is covalently bonded to three hydrogen atoms.The fourth hydrogen ion $(H^+)$ is attached to the nitrogen atom via a coordinate (dative) bond,where the lone pair on nitrogen is shared with the $H^+$ ion.Since the entire species carries a positive charge and exists as an ion,the interaction between the $NH_4^+$ cation and any counter-anion (like $Cl^-$ in $NH_4Cl$) is electrovalent (ionic) in nature.Thus,$NH_4Cl$ contains all three types of bonds.

Order	Property
$(A)$ $NO_2 > O_3 > H_2O$	Bond angle
$(B)$ $H_2O > HF > NH_3$	Dipole moment
$(C)$ $I_2 > F_2 > N_2$	Bond length

Which of the following molecules or ions possesses electrovalent,covalent,and coordinate bonds at the same time?
