Which of these is not a monomer for a high molecular mass silicone polymer? [NEET 2013]
A)\[MeSiC{{l}_{3}}\]
B)\[M{{e}_{2}}SiC{{l}_{2}}\]
C)\[M{{e}_{3}}SiCl\]
D)\[PhSiC{{l}_{3}}\]
Correct Answer:
C
Solution :
[c] is not a monomer for a high molecular mass silicone polymer because it generates Me3SiOH when subjected to hydrolysis which contains only one reacting site. Hence, the polymerisation reaction stops just after first step.
