The Lewis acid character of boron tri halides follows the order:
$BBr _3 > BI _3 > BCI _3 > BF _3$
$BCl _3 > BF _3 > BBr _3 > BI _3$
$BF _3 > BCl _3 > BBr _3 > BI _3$
$BI _3 > BBr _3 > BCl _3 > BF _3$
In the electrolysis of alumina, cryolite is added to
When metal $X$ is treated with sodium hydroxide, a white precipitate $(A)$ is obtained, which is soluble in excess of $NaOH$ to give soluble complex $(B)$. Compound $(A)$ is soluble in dilute $HCl$ to form compound $(C)$. The compound $(A)$ when heated strongly gives $(D)$, which is used to extract metal. Identify $(X), (A), (B), (C)$ and $(D)$. Write suitable equations to support their identities.
