The conjugate bases for Brönsted acids, H2SO4, and HCO3- will be, respectively:
1. ,
2. HSO4-, CO3-
3. SO4-2, CO32-
4. HS2O4-, CO32-
OH– , F– , H+ and BCl3
The species described above that contain Lewis acids are:
1. BCl3 and F-
2. OH– and F-
3. H+and BCl3
4. F- and BCl3
Assertion: acts as both Bronsted Lowry base as well as Lewis base.
Reason: It acts as both acceptor and a lone pair donor.
1. Both assertion & reason are true and the reason is the correct explanation of the assertion.
2. Both assertion & reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is a true statement but the reason is false.
4. Both assertion and reason are false statements.
