The p-Block Ele...

The geometry of a complex species can be understood from the knowledge of type of hybridisation of orbitals of central atom. The hybridisation of orbitals of central atom in $$[B(OH_4)]^-$$ and the geometry of the complex are respectively:

The exhibition of the highest co-ordination number depends on the availability of vacant orbitals in the central atom. Which of the following elements is not likely to act as a central atom in $$MF_6^{3-}$$?

Clay is used for making bricks and flower pots. If the clay article is not dried before 'firing' in a kiln, there will be evaporation of water from the surface and the :

Elements of group 14 exhibit oxidation sate of:

Which is not correct?

Element $$M+{ N }_{ 2 }\xrightarrow [  ]{ \Delta  } \xrightarrow [  ]{ { H }_{ 2 }O } { NH }_{ 3 }$$
Element $$M$$ belonging to group $$13$$ can be ?

Which of the following statements is correct with respect to the property of elements with increase in atomic number in the carbon family (group 14)?

Silicon has a strong tendency to form polymers like silicones. The chain length of silicone polymer can be controlled by adding:

The element with atomic number $$33$$ belongs to:

Assertion : The heavier p-block elements do not form strong $$\pi$$ bonds.
Reason : The heavier elements of p-block form $$d\pi-d\pi$$ bonds.
