$a, c$ and $d$

Vedclass · Answer

(B) Statement $(a)$ is correct: Linear silicones are formed by the polymerization of $(R_2SiO)_n$ units.Statement $(b)$ is incorrect: Hydrolysis of $RSiCl_3$ leads to the formation of cross-linked silicones,not linear ones. Linear silicones are formed from $R_2SiCl_2$.Statement $(c)$ is correct: Silicones are chemically inert and have high thermal stability,making them excellent heat insulators.Statement $(d)$ is correct: Silica $(SiO_2)$ reacts with $HF$ to form silicon tetrafluoride $(SiF_4)$ and water,which further reacts to form fluorosilicic acid $(H_2SiF_6)$,thus dissolving it.Therefore,statements $(a), (c),$ and $(d)$ are correct.

Consider the following statements:
$(a)$ $R_2SiO$ is the repeating unit of linear silicones.
$(b)$ $RSiCl_3$ on hydrolysis followed by dehydration gives linear silicones.
$(c)$ Silicones can be used as heat insulators.
$(d)$ Silica is soluble in $HF$.
The correct statement$(s)$ is/are:
