Chemistry - CHEMICAL BONDING Question with Solution | TestHub
Consider the following statements:
(I) According to VSEPR theory, the two or three electron pairs of a multiple bond are treated as a single super pair.
(II) According to VSEPR theory, the valence shell is taken as a sphere with electron pairs localizing on the spherical surface as close as possible to each other.
(III) Promotion of an electron to a higher energy level is an essential condition for hybridization.
(IV) Only filled orbitals can participate in the process of hybridization.
The correct statement(s) is/are:
Options:
Answer:
Solution:
Statement I is correct: a multiple bond is one electron domain in VSEPR.
II is false because electron pairs maximize separation.
III is false; promotion is not essential for hybridization.
IV is false because vacant orbitals may participate.
Therefore only I is correct.
