hydrogen bond and covalent bond

Covalent Bonding - Can we imagine a world without oxygen, nitrogen, water or carbon dioxide? Without any of these there would be no life at all. All the above mentioned compounds are covalent compounds formed by sharing of electrons. Non-metal atoms share the valence e..

Hydrogen Bond - Hydrogen bond is an intermolecular force of attraction that exists in the molecules that have hydrogen atom bonded to nitrogen, oxygen, or fluorine. Hydrogen bond is a strong dipole-dipole attraction. Wh..

. This may be represented as: The hydrogen atom acts as a bridge between two atoms, holding one atom by a covalent bond and the other atom by a hydrogen bond. The hydrogen bond is represented by dotted line (....) while the ..

The electrostatic force of attraction, which exists between the covalently bonded hydrogen atom of one molecule and the electronegative atom of the other molecule is known as hydrogen bond..

The bond between two unlike atoms, which differ in their affinities for electrons is said to be a polar covalent bond. When a covalent bond is formed between two atoms of different elements, the bonding pair of electrons will lie more tow..

Silicon carbide has also three-dimensional structure as of diamond, with each silicon atom surrounded by four carbon atoms and each carbon atom surrounded by four silicon atoms. Graphite has carbon atoms arranged in hexagonal parallel layers. This results in a double bond characteristic ..

Bond formed due to the sharing of three electron pairs is called a triple covalent bond or simply a triple bond. Three small horizontal lines between the two atoms denote a triple bond e.g., N N, and H-C C-H (acetylene..

Orbital Representation of Covalent Bonds - Covalent bonds are formed by the overlap of atomic orbitals. As orbitals have different shapes, it is difficult to represent the actual shape of the orbitals on the paper. Hence a pictorial notation is adopted with t..

. The total energy of the system is equal to the sum of the energies of the two H atoms. When the two atoms approach each other, electrons of one atom attract the nucleus of the other atom. Electrons of both the atoms are attracted by both the nuclei. These attractive interactions lead to..
