Answer:
The other may not be free.
Explanation:
In the polymer-supported reaction with methanol, the reaction will undergo at one hydroxyl group because others may not be free due to bonding with other molecules. The hydroxyl groups could be bonded with the polymer with the help of hydrogen bonding of molecules. The hydroxyl group has to be bonded to only the compatible molecules and free molecules.
We have that this is because of Chemoselective reaction where one functional group reacts before or in the presence of another.
Generally, A hydroxy is a group with there chemical formula represented as -OH, and are made up of one oxygen atom in a covalent bond with one hydrogen atom.
In polymer supported response of an alcohol with methanol selectively bear response at one hydroxy to the fact the every other hydroxy can also now not be free due to it may additionally linked with the polymer via H-bonding.
Therefore, Chemoselective reaction where one functional group reacts before or in the presence of another.
