Question:

Elements of group-$15$ form compounds in $+5$ oxidation state. However, bismuth forms only one well characterised compound in $+5$ oxidation state. The compound is

The Correct Option is B

Solution and Explanation

The stability of $+5$ oxidation state decreases down the group due to inert pair effect. The only well characterised $Bi(V)$ compound is $BiF_5$ as fluorine being most electronegative element is able to unpair $ns$ electrons.

P-Block Elements

  • P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
  • P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.

P block elements consist of:
