Substituted silanes give crosslinked silicone polymer upon hydrolysis. The correct option from the given substituted silanes is CH3SiCI3.
Explanation:
Silanes are compounds with the general formula SiHnXm, where X is a halogen or an organic group. Silanes undergo hydrolysis in the presence of water, resulting in the formation of siloxanes. Siloxanes are compounds with the general formula R2SiO, where R is an organic group. When silanes are substituted, they form crosslinked silicone polymers upon hydrolysis.
The given substituted silanes are:
a) (CH3)4Si
b) CH3SiCI3
c) (CH3)2SiCI2
d) (CH3)3SiCI
Out of the given options, CH3SiCI3 will give crosslinked silicone polymer upon hydrolysis. This is because CH3SiCI3 has one halogen atom and two organic groups attached to the silicon atom. The organic groups are capable of crosslinking with other siloxane chains, resulting in the formation of a three-dimensional network of silicone polymers.
The other options do not have the necessary substituents required for crosslinking. (CH3)4Si does not have any halogen or organic group attached to the silicon atom, while (CH3)2SiCI2 and (CH3)3SiCI have only one organic group and one halogen atom attached to the silicon atom, respectively. Therefore, they cannot form crosslinked silicone polymers upon hydrolysis.
In conclusion, CH3SiCI3 is the correct option among the given substituted silanes that will give crosslinked silicone polymer upon hydrolysis due to the presence of two organic groups attached to the silicon atom.
