Which type of intermolecular force is pbr3

Dipole-dipole interactions is found in PBr₃

Intermolecular forces are the forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions ). These forces are weak compared to the intramolecular forces (covalent or ionic bonds)

Types of Intermolecular Forces are Dispersion, Dipole–Dipole, Hydrogen Bonding, and Ion-Dipole.

Dipole-dipole interactions are intermolecular attractions that result from two permanent dipoles interacting. This is found in PBr₃, SO₂, I₂, and CO₂.

Dipole-dipole attractions

Explanation:

PBr₃ is a trigonal pyramidal 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.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
