Arrange the following substances in order of increasing boiling points: C2H5Cl, CH4 and C2H6. Explain your order by comparing the relative magnitudes and nature of the intermolecular force.

識唔識做?
thx~

CH4 < C2H6 < C2H5Cl.....

[QUOTE=霆鋒]CH4 < C2H6 < C2H5Cl.....[/QUOTE]我都係咁諗

molecular mass: C2H5CL>C2H6>CH4
C2H5CL有dipole~~其他冇
咁答已經好掂~~~

未夠.....要答埋
because molecular mass: C2H5CL>C2H6>CH4 , so分子間o既 van der 華力 C2H5CL>C2H6>CH4

我估~
