There are two hydrogen … WebA halogen bond occurs when there is evidence of a net attractive interaction between an electrophilic region associated with a halogen atom in a molecular entity and a nucleophilic region in another, or the same, molecular entity. [1] Like a hydrogen bond, the result is not a formal chemical bond, but rather a strong electrostatic attraction.
Web2 apr. 2014 · Answer link. Judy O. Apr 2, 2014. The two strands of DNA stay together by H bonds that occur between complementary nucleotide base pairs. Two hydrogen bonds occur between the adenosine and the thymine base pairs, and between the cytosine and the guanine there are three. While each hydrogen bond is extremely weak (compared to a …
WebOne molecule of hydrogen dissociates into two atoms (H2 → 2H) when an energy equal to or greater than the dissociation energy (i.e., the amount of energy required to break the bond that holds together the atoms in the molecule) is supplied.
