Hello students in this question basically we have to find out the which has the highest delta h fiparization these compounds are given firstly we have to know about the enthalpy of vaporization this is basically the presentation of the enthalpy of vaporization and we know that what is the enthalpy of vaporization enthalpy of vaporization is basically that how much amount of the heat is required to break the to convert the liquid to gas because vaporization process which is basically he represents as the liquid is equivalent with gas so liquid state is equivalent with gas so we can say that the help of vaporization is how much amount of the heat is required to convert of the liquid into gas so that is the therapy of vaporization as we can see that in these whole molecules all when h2 here is a h2 and f2 both are the diatomic molecules.
01:03
Both are the diatomic molecules.
01:08
Thus we can say that both for the biotomic molecules it is very difficult to get some type of the enthalpy or energy to break it, convert into the liquid to gas.
01:20
So we can say that.
01:21
And therefore the diatomic molecule h2 and f2 the value of enthalpy of vaporization and, is very low value and for this rn is a noble gas or we can say that noble gas or we can say that inert gas this can't react with anyone so for this also it can't easily convert into other forms so we can say that for this is also enthalpy of vaporization is a low and for another molecules that are sif4 and c6 h6 and these both are the covalent compounds and covalent compounds so due to the covalent compounds due to the covalent nature of the compound covalent compound are those in this case and the bond formation is occurred by the sharing of the electrons so these are the covalent compounds, sif4 and c6h6 due to this, these are covalent compound.

So we can say that the value of the enthalpy of vaporization for this compound is moderate, not less, not more, it is just moderate.
02:48
But if we have to find out an answer of this question which has the highest enthalpy of vaporization, then we can say that the sif4 is that molecule in whole option, which has the which has highest value of the enthalpy of vaporization value...
