Strongest hydrogen bond is present in:
Strength of hydrogen bond depends on the electronegativity of the atom with which hydrogen atom is attached.
In solid ammonia, each $${NH}_{3}$$ molecule has six other $${NH}_{3}$$ molecules as nearest neighbours. $$\Delta H$$ of sublimation of $${NH}_{3}$$ at the melting point is $$30.8kJ$$ $${ mol }^{ -1 }$$ and the estimated $$\Delta H$$ of sublimation in the absence of hydrogen bonding is $$14.4kJ$$ $${ mol }^{ -1 }$$. What is the strength of hydrogen bond in solid ammonia in $$kJ$$ $${ mol }^{ -1 }$$? Give your answer in nearest integer number.
Hydrogen bond is strongest in:
$$Ka_{2}$$ of Maleic acid is lesser than $$Ka_{2}$$ of fumaric acid due to:
Arrange the following as stated. Increasing strength of hydrogen bonding (X-H-X). $$O,S,F,Cl,N$$
Which of the following hydrogen bonds are strongest in vapour phase?
Define hydrogen bond. Is it weaker or stronger than the Van der Waals forces?
Which of the following has strongest bond?
Hydrogen bonds are formed in many compounds e.g., $$H_2O, HF \ and \ NH_3$$. The boiling point of such compounds depends to a large extent on the strength of the hydrogen bond and the number of hydrogen bonds. The correct decreasing order of the boiling points of the above compounds is :
Among NH3,H2O,HF and H2S which have the highest magnitude of hydrogen bonding?
Hydrogen bonding is maximum in
