By arranging the data rather differently it is easy to see 

 that the abnormality lies entirely with the hydroxyl group. 

 Thus, if we take any group of sulphur compounds of one type, 

 we shall find the boiling-point increases with the molecular 

 weight as well when the hydrogen of the SH group is 

 replaced by a hydrocarbon radical as in any other case.
