  • question_answer
    Among the following substituted silanes the one which will give rise to cross linked silicone polymer on hydrolysis is

    A) \[{{R}_{4}}Si\]                        

    B) \[{{R}_{2}}SiC{{l}_{2}}\]

    C) \[RSiC{{l}_{3}}\]                     

    D) \[{{R}_{3}}SiCl\]

    Correct Answer: A

    Solution :

    [c] The cross linked polymers will be formed by \[RSiC{{l}_{3}}\] \[nRSiC{{l}_{3}}\xrightarrow[-3nHCl]{3n{{H}_{2}}O}nR-\underset{OH}{\overset{OH}{\mathop{\underset{|}{\overset{|}{\mathop{Si}}}\,}}}\,-OH\xrightarrow{{}}\]
