Question

Silicon has a strong tendency to form polymers like silicones. The chain length of silicones polymer can be controlled by adding:

• A. $MeSiC{l}_3$
• B. $M{e}_{2}SiC{l}_2$
• C. $M{e}_{3}SiCl$
• D. $M{e}_{4}Si$

Answer 1

The correct option is C $M{e}_{3}SiCl$

The chain length of Silicone polymer can be controlled by adding $(C{H}_3{)}_{3}SiCl$, which blocks the ends as shown below:


Hence, the correct answer is option (c).
