Assertion : Si-Si bond is stronger than ...

Assertion : Si-Si bond is stronger than Si-O bond.
Reason: Silicon form Si-Si bond easily.

A

Both A and R are true and R is the correct explanatoin of A

B

both A and R are true but R is the correct explanation of A

C

A is true but R is false

D

Both A and R are false

Text Solution

Verified by Experts

The correct Answer is:
D
Si-O bond is stronger than Si-Si bond and `p pi-d pi` bonding between silicon atoms is not possible due to its larger size.
