Hydrazine, N,H4, is a compound that is very soluble in water and has a boiling point of 113°C at standard pressure. Unlike water, hydrazine is very reactive and is sometimes used as a fuel for small rockets. One hydrazine reaction producing gaseous products is represented by the balanced equation below. N2H4 (1) → N2 (g) + 2H2 (g) + heat A. The electronegativity value of nitrogen is 3.0 and that of hydrogen is 2.1. Based on the electronegativity difference, identify the type of bond in hydrazine, N,H4. B. Explain in terms of polarity, why hydrazine, N,H4, is very soluble in water. C. Explain, in terms of intermolecular forces, why the boiling point of hydrazine is so high at standard pressure. D. Compare the atomic radius of nitrogen, N2 and hydrogen, H2. Justify your answer.
Types of Chemical Bonds
The attractive force which has the ability of holding various constituent elements like atoms, ions, molecules, etc. together in different chemical species is termed as a chemical bond. Chemical compounds are dependent on the strength of chemical bonds between its constituents. Stronger the chemical bond, more will be the stability in the chemical compounds. Hence, it can be said that bonding defines the stability of chemical compounds.
Polarizability In Organic Chemistry
Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization.
Coordinate Covalent Bonds
A coordinate covalent bond is also known as a dative bond, which is a type of covalent bond. It is formed between two atoms, where the two electrons required to form the bond come from the same atom resulting in a semi-polar bond. The study of coordinate covalent bond or dative bond is important to know about the special type of bonding that leads to different properties. Since covalent compounds are non-polar whereas coordinate bonds results always in polar compounds due to charge separation.
