The main reason that S i C l 4 is easily hydrolysed as compared to C C l 4 is that
Options
- AS i - C l bond is weaker than C - C l bond
- BS i C l 4 can form hydrogen bonds
- CS i C l 4 is covalent
- DSi can extend its coordination number beyond four
Correct answer
D. Si can extend its coordination number beyond four
Step-by-step solution
Silicon has got vacant 'd' oribtals but carbon does not have that moreover Silicon, also has larger size than carbon so silicon can have extended valency rather extended coordination number 6 also.
