JEE Mains · Chemistry · STD 11 -p-Block elements - I
Given below are two statements :
Statement I: The number of pairs among [ \( SiO_{2}, CO_{2} \)], [SnO, \( SnO_{2} \)], [PbO, \( PbO_{2} \)] and [GeO, \( GeO_{2} \)], which contain oxides that are both amphoteric is 2.
Statement II: \( BF_{3} \) is an electron deficient molecule can act as a lewis acid, forms adduct with \(NH _3\) and has a trigonal planar geometry.
In the light of the above statement, choose the correct answer from the option given below.
- A Both Statement I and Statement II are true.
- B Both Statement I and Statement II are false.
- C Statement I is true but Statement II is false.
- D Statement I is false Statement II is true.
Answer & Solution
Correct Answer
(A) Both Statement I and Statement II are true.
Step-by-step Solution
Detailed explanation
\( SiO_{2}, CO_{2}, GeO, GeO_{2} \) are acidic in nature. SnO, \( SnO_{2}, PbO, PbO_{2} \) are amphoteric in nature. → \( BF_{3} \) is lewis acid according to Lewis octet theory and has \( sp^{2} \) hybridization with trigonal planar geometry and it can accept lone pair from…
