Question

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.

• A. Both statement I and Statement II are true
• B. Both statement I and Statement II are false
• C. Statement I is true but Statement II is false
• D. Statement I is false but Statement II is true

Answer 1

Answer: (D)

$Be _2 Cl _4$ 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.
