Even though a hydrogen bond is only 5% as strong as a covalent bond, it’s enough to stabilize water molecules. Hydrogen bonding causes water to remain liquid over a wide temperature range. As it takes extra energy to break hydrogen bonds, water has an unusually high heat of vaporization. Water has a much higher boiling point than other hydrides.
Hydrogen bond is a electrostatic attraction between a hydrogen atom which is bond to a more electronegative atom such as Nitrogen, Oxygen, fluorine. These are two types of hydrogen bonds :- 1) Intermolecular Hydrogen bonding :- It occurs between two separate molecules.
1. Intermolecular hydrogen bond. 2. Intermolecular hydrogen bond. 1. Intermolecular hydrogen bond : Electrostatic force of attraction that exists between hydrogen atom of one molecule and electronegative atom of another molecule is called intermolecular hydrogen atom . Example: H 2 O. 2. Intra molecular Hydrogen bond : Electrostatic force of ...
H. C. l. although. C. l. is quite electronegative. Despite its electronegativity, size of a chlorine atom is larger and hence, the electron density is low. So, HCl does not have hydrogen bonding but, H F,N H 3,H 2O shows hydrogen bonding.
As fluorine has small size and high electronegativity, it has high tendency to attract partial positive charge accumulated on H-atom. So, fluorine forms strongest H-bond. Was this answer helpful? Which is the strongest hydrogen bond and the weakest hydrogen bond in the following. 1)H2S,H2O. 2) H2O,H2S. 3)NH3,C2H5OH. 4)C2H5OH,NH3.
Verified by Toppr. A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F) experiences attraction to some other nearby highly electronegative atom. These hydrogen-bond attractions can occur between molecules ...
A hydrogen bond is a type of attractive (dipole-dipole) interaction between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This bond always involves a hydrogen atom. Hydrogen bonds can occur between molecules or within parts of a single molecule. A hydrogen bond tends to be stronger than van-der Waal's ...
These hydrogen-bond attractions can occur between molecules (intermolecular) or within different parts of a single molecule (intramolecular). The hydrogen bond (5 to 30 kJ/mole) is stronger than a van der Waals interaction, but weaker than covalent or ionic bonds. This type of bond can occur in inorganic molecules such as water and in organic ...
Hydrogen bonds are formed in many compounds e.g., H 2 O, H F, N H 3. The boiling point of such compounds depends to a extent on the strength of hydrogen bond and the number of hydrogen bonds. The correct decreasing order of the boiling points above compounds is (a) H F > H 2 O > N H 3 (b) H 2 O > H F > N H 3 (c) N H 3 > H F > H 2 O (d) N H 3 ...
Liquid N H3. Solution. Verified by Toppr. H Cl does not form hydrogen bonds because chlorine is not electronegative enough, and it has larger size, so hydrogen bonds are not formed. They are generally formed with fluorine, oxygen, and nitrogen. Thus, phenol, liq ammonia and water forms hydrogen bonds.
