Hydrogen bonding is a type of dipole dipole interaction. It exist between H atom bonded to electronegative atom; O, N, F and other O, N, F of another molecule.
Some of the examples of compounds having hydrogen bonding are:
Hydrogen bonding exists because of development of dipole dipole interaction between H and electronegative atom.
As H is less electronegative as compared to O, N and F. So partial positive charge develop on H and partial negative chagre develop develop on the attached electronegative atom. Because of development of partial positive and partial negative charge, dipole dipole interaction occurs which leads to the development of hydrogen bonding.
Hydrogen bonds are special dipole-dipole attraction between polar molecules in which a hydrogen molecule atom is directly joined to a highly electronegative atom.
This type of bond is an intermolecular bond caused by an electrostatic attraction between the hydrogen atom of one molecule and the electronegative atom(O or N or F) of a neighbouring molecule.
Determining flammability can be as simple as holding a sample of the substance over a match. If it burns, it is flammable, leading to additional experiments to find more properties. Measuring the heat given off by the substance when it burns gives the heat of combustion.
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
Non metals (It’s both halogens and noble gases ) the other ones which are white(not highlighted) are alkali metals, alkaline earth metals, and transition metals :3
