The H-C-H bond angles in acetic acid,shown below,are closest to O CH₃C-OH

Question

Quizplus · Accepted Answer

The H-C-H bond angles in acetic acid are determined by the hybridization state of the carbon atom. In acetic acid, the carbon atom is sp2 hybridized, meaning that it is bonded to three atoms and has one lone pair of electrons. This results in a trigonal planar geometry with bond angles of approximately 120°. However, the presence of the lone pair on the carbon atom will distort the geometry slightly, leading to bond angles that are slightly less than 120°. Therefore, the closest answer choice is B (109.5°), which corresponds to the bond angles of a sp3 hybridized atom in a tetrahedral geometry.
