Which type of intermolecular force is PBr3
1 answer:
Answer:
Dipole-dipole attractions
Explanation:
PBr₃ is a <em>trigonal pyramidal</em> molecule.
The P-Br bonds are polar, with their bond dipoles pointing toward the Br atoms (see below).
The x-components of the dipoles cancel, but the y-components reinforce each other.
The partially negative Br atoms are attracted to the partially positive N atoms in neighboring molecules.
These dipole-dipole forces are the strongest intermolecular forces in PBr₃.

Explanation:
The element with electron configuration 1s22s22p63s1 belong I A group in the periodic table and it is sodium because it loses one electron.
We have periodic table in attachments.
Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell, which it readily donates, creating a positively charged ion—the Na+ cation. Its only stable isotope is 23Na.
The free metal does not occur in nature, and must be prepared from compounds.
It is soft metal, reactive and with a low melting point.
