Of the following,which molecule has the largest bond angle? A)O₃ B)OF₂ C)HCN D)H₂O E)More than one of the above have equally large bond angles.

Question

Quizplus · Accepted Answer

HCN has the largest bond angle of 180 degrees, as it is a linear molecule with a triple bond between the carbon and nitrogen atoms. Choice A and B both have sulfur atoms which are larger than oxygen atoms and would therefore have smaller bond angles. Choice D has a bent shape and a smaller bond angle of approximately 109.5 degrees due to the lone pair on the oxygen atom.
