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.
acquired traits are traits that organisms develops over a lifetime. adaptation are trait that enhances an organism's ability to survive and reproduce in its environment.
the sperm cell contributes half of the chromosome in an offspring while the egg cells contributes the other half. Hence, the sperm cell has half of 26, 13. This process is called meiosis. Meiosis is when one cell undergoes cell division twice, thus creating 4 new cells. Each of these 4 new cells have half the amount of chromosomes as the original cell.
