Be and Al show similarities in properties due to diagonal relationship except in the property X given below. What is X ?
Options
- ABoth form basic oxides and hydroxides
- BIons of both have strong tendency to form complexes
- CIn vapour phase chlorides of both have Cl ⁻ bridged chloride structure
- DChlorides of both are soluble in organic solvents
Correct answer
C. In vapour phase chlorides of both have Cl ⁻ bridged chloride structure
Step-by-step solution
The oxides and hydroxides of both Be and Al are amphoteric and dissolve in sodium hydroxide solution as well as in hydrochloric acid. aligned & BeO +2 HCl BeCl ₂+ H ₂ O & BeO +2 NaOH Na ₂ BeO ₂+ H ₂ O & Al ₂ O ₃+6 HCl 2 AlCl ₃+3 H ₂ O & Al ₂ O ₃+2 NaOH 2 NaAlO ₂+ H ₂ O aligned
