Textbook Problem

Which of the following elements are capable of forming hypervalent compounds?

  1. (a) C
  2. (b) P
  3. (c) O
  4. (d) F
  5. (e) Cl
  6. (f) B
  7. (g) Se
  8. (h) Sn

Interpretation Introduction

Interpretation: The elements that are capable of forming hypervalent compounds should be identified.

Concept Introduction:

Hypervalent: The compounds that are formed by combination of third or higher period’s elements which are surrounded by more than four electron pairs that is the central atom exceeds the octet rule hence such elements are termed as hypervalent.

Octet rule: By obtaining eight electrons around the valence shell of an element, then compound satisfied the octet rule and thus, achieved the electron configuration of noble gas.

Explanation

Reasons for correct answer:

Generally, elements that are capable of forming compounds by expanding their valency that is exceeding the octet and gets surrounded by more than four electron pairs are termed as hypervalent. Elements present in third or higher period’s element form hypervalent compounds.

Analyzing the periodic table shows that from the given elements only (b)Pand(e)Cl belong to third period also that (g)Seand(h)Sn belongs to higher periods therefore only (b)P,(e)Cl,(g)Seand(h)Sn elements form hypervalent compounds
