List-I | List-II |
(A) XeF2 | (iii) Linear |
(B) BF3 | (i) Trigonal Planar |
(C) XeF4 | (ii) Distorted Octahedral |
(D) SF6 | (iv) Regular Octahedral |
The molecular geometries are from VSEPR:
• \(XeF_2\): Linear due to three lone pairs and two bond pairs.
• \(BF_3\): Trigonal planar due to three bond pairs and no lone pairs.
• \(XeF_4\): Distorted octahedral with four bond pairs and two lone pairs.
• \(SF_6\): Regular octahedral with six bond pairs and no lone pairs.
The correct matching is: (A) - (iii), (B) - (i), (C) - (ii), (D) - (iv).
Europium (Eu) resembles Calcium (Ca) in the following ways:
