Respuesta :
As only polar molecule dissolve in polar solutions therefore H₂S will dissolve in NH₃.
The complete question is
Which compound listed below will dissolve in NH3? A) O2 B) CO2 C) H2S D) all of the compounds E) none of the compounds Please explain why the answer is C and not A or B
What is a polar molecule ?
Polar molecule is joined by Ionic Bond , or it can be said as when two atoms form a molecule by giving and taking of a electron then it is called a polar molecule.
To understand which compound will dissolve in NH₃ ,
Because it has three bonded atoms and one lone pair, and each of those bonds is polar, it is trigonal pyramidal.
because each bond is polar and the molecule is asymmetric, we get a polar molecule.
O₂
In this bond the bond is between Oxygen -Oxygen and as the elctronegativity of both the atoms in the bond is same.
This is a non polar molecule.
Carbon dioxide
It does have two polar bonds, but it is linear, so it is symmetrical and therefore even though it has polar bonds, it is a non polar molecule because opposite polar bonds cancel each other .
H₂S
As sulfur has six valence electrons, each hydrogen has one.
So it is a bent molecule.
The bonds on this are not polar but are asymmetrical and so behaves like polar.
As only polar molecule dissolve in polar solutions therefore H₂S will dissolve in NH₃.
