Q. Which of the following can be used as anesthetic?

Q. Regarding dipole moment of the following species.
$C{H}_4,C{H}_{3}Cl,C{H}_{2}C{l}_2,CHC{l}_3,CC{l}_4$
Zero : $CC{l}_4$
Maximum : $C{H}_{3}Cl$
Order being : $C{H}_4=CC{l}_4<CHC{l}_3<C{H}_{2}C{l}_2<C{H}_{3}Cl$
If true enter 1, else enter 0.

Q. A solution is prepaired by mixing $8.5g$ of $C{H}_{2}C{l}_2$ and $11.95g$ of $CHC{l}_3$. If vapour pressure of $C{H}_{2}C{l}_2$ and $CHC{l}_3$ at $4298K$ are $415$ and $200mmHg$ respectively, the mole fraction of $CHC{l}_3$ in vapour form is : (molar mass of $Cl=35.5gmo{l}^{-1}$)
