Final answer:
The difference between ROH and a dash OH lies in the presence of hydrogen. ROH represents an alcohol and is basic, while a dash OH represents an ether and is azoic in behavior.
Step-by-step explanation:
Of the two hydroxy organic compounds ROH and a dash OH, the first one is basic, and the other is azoic in behavior. The difference between ROH and a dash OH lies in the presence of hydrogen.
ROH represents an alcohol, which contains an -OH group bonded to a carbon atom. This -OH group is responsible for the basic behavior of the compound. When ROH dissolves in water, it does not dissociate into ions, but it can accept a proton (H+) from a strong acid, making it basic.
On the other hand, a dash OH represents an ether, which contains an oxygen atom bonded to two alkyl or aryl groups (R and R'). Since it does not have a hydrogen atom bonded to the oxygen, it cannot accept a proton and therefore does not exhibit basic behavior. It is azoic in behavior.
