When a hydrogen bond is sandwitched between two highly electronegative elements

(F, O, N)

, it shows a unique property to form a bridge between them which is termed as hydrogen bond. Its strength depands upon the electronegativity of associated atom. Thus, the order of hydrogen bond must be

H F_{2}^{-} > H F > H_{2} O > N H_{3}

Q. The hydrogen bonds are encountered in $H F, H_{2} O, N H_{3}$ and $H F_{2}^{-}$ . The relative order of energies of hydrogen bonds is

$H F > H_{2} O > N H_{3} > H F_{2}^{-}$

$H_{2} O > H F_{2}^{-} > H F > N H_{3}$

$H F > H F_{2}^{-} > H_{2} O > N H_{3}$

$H F_{2}^{-} > H F > H_{2} O > N H_{3}$

Q. The hydrogen bonds are encountered in HF,H2​O,NH3​ and HF2−​ . The relative order of energies of hydrogen bonds is

HF>H2​O>NH3​>HF2−​

H2​O>HF2−​>HF>NH3​

HF>HF2−​>H2​O>NH3​

HF2−​>HF>H2​O>NH3​

Q. The hydrogen bonds are encountered in $H F, H_{2} O, N H_{3}$ and $H F_{2}^{-}$ . The relative order of energies of hydrogen bonds is

$H F > H_{2} O > N H_{3} > H F_{2}^{-}$

$H_{2} O > H F_{2}^{-} > H F > N H_{3}$

$H F > H F_{2}^{-} > H_{2} O > N H_{3}$

$H F_{2}^{-} > H F > H_{2} O > N H_{3}$
