Chemistry
1 answer:
MissTica3 years ago
6 0
The trend of electronegativity in the periodic table is increasing from left to right and from bottom to top. In the period 4 which is horizontal, the element which has the highest electronegativity is the right most element except the noble gas. This element is bromine.

Lera25 [3.4K]

Answer:

NH3 has greater water solubility due to intermoleculate interactions

Explanation:

Hi:

If we represent the structures of NH3 and SbH3 we can see that they are similar to the naked eye, this is because N and Sb belong to the same group of the periodic table (group 15).

However, the electronegativity of N is greater than that of Sb. The NH3 molecule is polar and can form an intermolecular interaction called hydrogen bridge with water.

Sb is less electronegative than N. The SBH3 molecule forms an intermolecular interaction with water called dipole-induced dipole.

The zone with positive charge density of the water molecule (hydrogens) is oriented towards the zone with positive charge density of SBH3 (the pair of electrons not shared)

Stronger intermolecular junctions allow greater solubility of NH3 molecules.
