Question

State octel rule. Explain its inadequecies
with respect to
a. Incomplete octel b. Expanded ​

Answer 1

Explanation:

A

Incomplete Octet. ... When this occurs, the atom of the element within the molecule is said to contain an incomplete octet. The common examples of such elements are hydrogen (stable with only 2 valence electrons), beryllium (stable with only 4 valence electrons) and boron and aluminum (stable with only 6 valence electrons) .

B

The common examples of such elements are hydrogen (stable with only 2 valence electrons), beryllium (stable with only 4 valence electrons) and boron and aluminum (stable with only 6 valence electrons). ... Expanded octet occurs when an atom is able to have more than 8 valence electrons.

Answer 2

Answer:

octet rule states that, " atoms form bond in order to have a stable eight electron configuration to have stability".

a) when we consider boron as an example when it forms bond with other elements it do not have a octet configuration so it is said to be incomplete octet

b) expanded means when sulphur and phosphorus makes bond with other elements it has extra electrons than required so it is said to have expanded octet
