This question we are given the compounds, pentane, butanel and one butanol.
00:07
So now we need to arrange them in their increasing boiling point order.
00:12
So, pentane, this is a hydrocarbon.
00:21
Then we have butanel, so this is an aldehyde.
00:27
And then we have one butanol, this is an al -dehyde.
00:33
So, what we know in case of alcohol is that there is the presence of intermolecular hydrogen bonding.
00:55
And that is why the boiling point of alcohols is higher.
01:06
So out of pentane, butanil and one butanol, one butanol will have the highest boiling boiling point.
01:23
Now the comparison is between pentane and butanil.
01:27
So, butanel, which is an aldehyde, this is a polar molecule.
01:36
And that is why here there will be intermolecular dipole -draction.
01:57
But in case of pentane, which is a hydrocarbon, which is a hydrocarbon, but in case of carbon, this will have the weak vanderwals force.
02:13
That is why the order will be, pentane will have the least boiling point because of weak van der waals forces.
02:24
Then we will have butanil and it will be the highest for one butanol...
