In the given question 5 compounds are given.
00:04
We need to find which molecule having lowest boiling point.
00:12
So the given molecules are c5h 12, c6h 14, c7 h 16, c8 h18 and finally c9 h20.
00:28
All these 5 structures following the formula cn h2n plus.
00:33
2 which is the general form for alkanes.
00:39
So we know that the simplest form of alkan is methane.
00:44
So in case of methane the forces will be very small.
00:54
Next we can discuss about propane, cs3, ch2, cs3.
01:00
In this case we can say that there will be dispersion force.
01:13
If in the case of pendane it will be cs3, ch2, ch2, ch2, ch2, ch2, cs3...
