The tendency of X in `BX_(3)(X=F,Cl,Ome, Nme)` to form a `pi` bond with boron follows the order

The Lewis acid nature of BX_(3) follows the order:

The tendency to form the anion X^(-) is greatest with

The tendency to form p_(pi) - p_(pi) multiple bonds in group 14 is most prominent for

As the tendency to from p pi-dpi bond decreases, the tendency for the polymerisation increases. So the correct order of tendency of polymerisation is :

Consider the following information (F=F or Cl) According to given information choose the incorrect order of bond length :

Consider the following information (F=F or Cl) According to given information choose the incorrect order of bond length :

The total number of boron - oxygen bonds in borax is 'x' and boron - oxygen - boron bonds are 'y'. Then the value of x-y is :

The total number of boron - oxygen bonds in borax is 'x' and boron - oxygen - boron bonds are 'y'. Then the value of x-y is :
