Question

Regarding PH3 , incorrect statement
(A) It is electron rich
hydride
(B) It has one lone pair
on central atom
(C) PH3 further cannot
convert to PH
(D) It has more than
octet on central atom​

Answer 1

Answer:

(B) it has one line pair on central atom

Answer 2

The incorrect statement regarding PH3 is:

(D) It has more than  octet on central atom​.

- PH3 is a hydride of phosphorous.

- The element phosphorous has 5 electrons in its outer shell (valence shell).

- It forms PH3 by forming three covalent bonds due to sharing of 3 electrons with the hydrogen atoms.

- That sums up to 8 electrons for phosphorous.

- So, the octet of PH3 gets completed and it does not have the expanded octet of the central atom.
