Arrange the following compounds in the increasing order of their boiling points :
`CH_3 CHO ,CH_2OH ,CH_3 OCH_3 , CH_3 CH_2 CH_3`

Explanation

To arrange the compounds in the increasing order of their boiling points, we need to consider the types of intermolecular forces present in each compound. The compounds given are:

1. CH₃CHO (Acetaldehyde)
2. CH₃CH₂OH (Ethanol)
3. CH₃OCH₃ (Dimethyl ether)
4. CH₃CH₂CH₃ (Propane)
