Choose the correct sequence for the geometry of the given molecules Borazone, Borazole, $B_3O_6^{-3}$ , $Fe_2Cl_6$, trimer of $FCN$. [$'P'$ stands for planar and $'NP'$ stands for non-planar]
Colour of the bead in borax bead test is mainly due to the formation of
Given below are two statements :
Statement $I$: In group $13$, the stability of $+1$ oxidation state increases down the group.
Statement $II$: The atomic size of gallium is greater than that of aluminium.
In the light of the above statements, choose the most appropriate answer from the options given below:
The stability of $+ 1$ oxidation state among $Al,Ga, In$ and $Tl$ increases in the sequence
Discuss the pattern of variation in the oxidation states of
$(i)$ $B$ to $Tl$ and $(ii)$ $C$ to $Pb$.
