Question

write positive and negative NH,OH​

Answer 1

Answer:

In molecules containing N-H, O-H or F-H bonds, the large difference in electronegativity between the H atom and the N, O or F atom leads to a highly polar covalent bond (i.e., a bond dipole). The electronegativities are listed below.

element

electronegativity value

H 2.1

N 3.0

O 3.5

F 4.1

Because of the difference in electronegativity, the H atom bears a large partial positive charge and the N, O or F atom bears a large partial negative charge.

A H atom in one molecule is electrostatically attracted to the N, O, or F atom in another molecule.
