TestHub · Accepted Answer

(i) BeCl₂ (g) → solid: linear (sp) changes to polymeric (sp³) → change

(ii) AlCl₃ (g) dimerization: sp² → sp³ (Al₂Cl₆ formation) → change

(iii) ICl₃ dimerization: becomes sp³d² (change)

(iv) B₂H₆ + NH₃: forms adduct, hybridization of B remains same

(v) NO₂ dimerization (N₂O₄): sp² → sp² (no change)

(vi) Given organic reaction with B₂H₆: no hybridization change at marked atom

(vii) CF₃ radical dimerization: sp³ → sp³ → no change

Total processes with hybridization change = 3
