Question

Which of the following is not the chain stopping unit in the preparation of silicones?

• A. $(C{H}_3{)}_{2}SiC{l}_2$
• B. $\left(C{H}_3\right)SiC{l}_3$
• C. $${\left(C{H}_3\right)}_{3}SiOSi{\left(C{H}_3\right)}_3$$
• D. $(C{H}_3{)}_{3}SiCl$

Answer 1

Answer: (A), (B), (C)

$${\left(C{H}_3\right)}_{3}SiOSi{\left(C{H}_3\right)}_3$$

$(C{H}_3{)}_{3}SiCl$ acts as chain stopping unit in the preparation of silicones.
