Vedclass · Answer

(A) The hydrolysis of chlorosilanes is the first step in the formation of silicones.$1$. $Me_3SiCl + H_2O \rightarrow Me_3SiOH + HCl$. This product $(A)$ has only one reactive site and acts as a $Terminal \ group$ to stop chain growth.$2$. $Me_2SiCl_2 + 2H_2O \rightarrow Me_2Si(OH)_2 + 2HCl$. This product $(B)$ has two reactive sites and acts as a $Chain \ forming \ group$ to extend the polymer chain.$3$. $MeSiCl_3 + 3H_2O \rightarrow MeSi(OH)_3 + 3HCl$. This product $(C)$ has three reactive sites and acts as a $Branching \ and \ bridging \ group$ to create cross-linked structures.Therefore,the correct sequence is $Terminal \ group$,$Chain \ forming \ group$,and $Branching \ and \ bridging \ group$.

Consider the following reactions:
$Me_3SiCl \xrightarrow{H_2O} A$
$Me_2SiCl_2 \xrightarrow{H_2O} B$
$MeSiCl_3 \xrightarrow{H_2O} C$
$A$,$B$,and $C$ are known as . . . . . . , . . . . . . ,and . . . . . . respectively in silicones formation.
