According to the VSEPR theory, which one of the following species should be linear? A)H₂S B)HCN C)BF₃ D)H₂CO E)SO₂

Question

Quizplus · Accepted Answer

The VSEPR theory states that a molecule's shape is determined by the number of electron pairs in its valence shell and the electron pairs' repulsion. HCN has a linear shape because the cyanide ion's negative charge repels the electrons in the C-N bond, causing them to spread out as much as possible. The other molecules in the list have more than two electron pairs, leading to different shapes.
