In context with beryllium, which one of the following statements is incorrect.

Given below are two statements:

Statement I : The chlorides of $\mathrm{Be}$ and $\mathrm{Al}$ have Cl-bridged structure. Both are soluble in organic solvents and act as Lewis bases.

Statement II: Hydroxides of $\mathrm{Be}$ and $\mathrm{Al}$ dissolve in excess alkali to give beryllate and aluminate ions. In the light of the above statements. Choose the correct answer from the options given below.

Among the statement (I – IV), the correct ones are:

(I) Be has smaller atomic radius compared to Mg.

(II) Be has higher ionization enthalpy than AI.

(III) Charge/radius ratio of Be is greater than that of Al.

(IV) Both Be and Al form mainly covalent compounds

Reaction of ${\mathrm{BeCl}}_2$ with ${\mathrm{LiAlH}}_4$ gives :

(A) ${\mathrm{AlCl}}_3$

(B) ${\mathrm{BeH}}_2$

(C) $\mathrm{LiH}$

(D) $\mathrm{LiCl}$

(E) ${\mathrm{BeAlH}}_4$
