Which of the following form dimeric halides
$Al$
$Ga$
$In$
All of the above
(d) $A{l_2}C{l_6},\,\,I{n_2}C{l_6},\,\,G{a_2}C{l_6}$
Colour of the bead in borax bead test is mainly due to the formation of
Anhydrous $AlCl_3$ is formed in
If $B-Cl$ bond has a dipole moment, explain why $BCl_3$, molecule has zero dipole moment.
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.
Hoop's process is used for the purification of the metal
