Chemistry - Complete Pblock- Question with Solution | TestHub
There are three elements and R which belong to p-block of the periodic table. They all form trifluorides with , such that is Lewis's acid but is a weaker Lewis base (dipole moment ). These two compounds react with each other in presence of to produce . The compound is inter halogen molecule. Which of the following is/are correct statements with reference to above information?
Options:(select one or more)
Answer:
Solution:
A. Incorrect. RF₃ (e.g., ClF₃) has unequal bond lengths.
B. Correct. RF₃ (e.g., ClF₃) is polar due to T-shaped geometry.
C. Correct. If P=B and Q=N, then B in BF₄⁻ and N in NF₄⁺ are both sp³ hybridized.
D. Correct. P=B, Q=N, R=Cl satisfy all conditions.
RF₃ (e.g., ClF₃) has a T-shaped geometry with lone pairs on the central atom, leading to unequal bond lengths and a net dipole moment. P=B and Q=N fit the Lewis acid/base properties, and in QF₄⁺PF₄⁻, both B and N are sp³ hybridized.
The final answer is B, C, D.
