Question

Match the column : List - I List - II (A) Dimer of BeCl 2 ​ (P) Neither lone pair nor vacant p-orbital in valance shell of central atom (B) Dimer of AlBr 3 ​ (Q) Non-planar and see-saw in shape (C) XeF 5 − ​ (R) Central atom (s) is/are electron deficient (S) Bond angles are 7 2 ∘

TestHub · Accepted Answer

BeCl₂ dimer (Be₂Cl₄): Each Be is electron-deficient (has <8 electrons). → R

AlBr₃ dimer (Al₂Br₆): Central Al atoms use all orbitals for bonding, no lone pair or vacant p-orbital. → P

Molecule with bond angles 72°: Likely a cyclopentane-like structure. → S
