JEE MAIN - Chemistry (2008 - No. 21)
Which one of the following is the correct statement?
Boric acid is a protonic acid
Beryllium exhibits coordination number of six
Chlorides of both beryllium and aluminium have bridged chloride structures in solid phase
B2H6.2NH3 is known as ‘inorganic benzene’
Explanation
The coordination number exhibited by beryllium is $$4$$ and not $$6$$ so statement $$(b)$$ is incorrect.
Both $$BeC{l_2}$$ and $$AlC{l_3}$$ exhibit bridged structures is solid state so $$(c)$$ is correct statement.
