MCQ
Oncontrolled hydrolysis and condensation, ${R_3}SiCl$ yields
  • ${R_3}Si - O - Si{R_3}$
  • B
    ($\,{R_3}Si - O - Si{R_3}\,$)$n$
  • C
    ${R_3}SiOH$
  • D
    $\mathop {\mathop {\mathop {\mathop {\mathop {\mathop {|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,|}\limits_{O\,\,\,\,\,\,\,\,\,\,\,\,\,\,O} }\limits_{ - Si - O - Si - } }\limits_{|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,|\,} }\limits^{ - Si\,\, - \,O\,\, - Si\, - } }\limits^{|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,|} }\limits^{R\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,R} $

Answer

Correct option: A.
${R_3}Si - O - Si{R_3}$
a
(a) ${R_3}SiCl$ on hydrolysis forms only a dimer.

${R_3}SiOH + HOSi{R_3} \to {R_3}Si - O - Si{R_3}$.
