Given below are two statements :
Statement I: The number of pairs among and , which contain oxides that are both amphoteric is 2 .
Statement II: is an electron deficient molecule, can act as a Lewis acid, forms adduct with and has a trigonal planar geometry.
In the light of the above statements, choose the correct answer from the options given below:

Statement I is true but Statement II is false

Both Statement I and Statement II are true

Both Statement I and Statement II are false

Statement I is false but Statement II is true

Text Solution

Verified by Experts

The correct answer is:

Statement I: Checking amphoteric nature of oxide pairs:
: Both acidic (non-metal oxides)
: Both amphoteric
is amphoteric but is predominantly acidic/oxidizing
: Both amphoteric (Ge is metalloid)
2 pairs have both oxides amphoteric. Statement I is true.
Statement II: has B with 6 valence electrons (electron deficient), acts as Lewis acid, forms adduct, has hybridization giving trigonal planar geometry. Statement II is true.
