Given below are two statements: Statement I: The chlorides of Be and Al have Cl-bridged structure. Both are soluble in organic solvents and act as Lewis bases. Statement II: Hydroxides of Be and 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.

Be 2 Cl 4 is lewis acid and Al 2 Cl 6 has complete octet. Be and Al are amphoteric metals therefore dissolve in acid as well as alkaline solution and form beryllate and aluminate ions in excess alkali.

Both statement I and Statement II are true

Both statement I and Statement II are false

Statement I is true but Statement II is false

Statement I is false but Statement II is true

Be2​Cl4​ is lewis acid and Al2​Cl6​ has complete octet. Be and Al are amphoteric metals therefore dissolve in acid as well as alkaline solution and form beryllate and aluminate ions in excess alkali.

$B e_{2} C l_{4}$ is lewis acid and $A l_{2} C l_{6}$ has complete octet. $B e$ and $A l$ are amphoteric metals therefore dissolve in acid as well as alkaline solution and form beryllate and aluminate ions in excess alkali.
