Propane Lewis Structure: Draw the Chain, Angles, and Shape

Propane, C3H8, has 20 valence electrons in ten single bonds and no lone pairs. Every carbon is tetrahedral, so each bond angle is about 109.5° and the carbon skeleton is a bent zigzag chain, not a straight line.

Question

Draw a line-bond structure for propane, CH3CH2CH3\mathrm{CH_3CH_2CH_3}. Predict the value of each bond angle, and indicate the overall shape of the molecule.

Evidence boundary

The three parts, their order, and the wording of the drawing request follow OpenStax Organic Chemistry Problem 1-8, which asks for a line-bond structure for propane, a prediction of each bond angle, and the overall shape. This page keeps the Lewis-structure framing used by the search keyword while drawing the same condensed formula, so the exercise asked does not change. Bond angles are quoted as approximate tetrahedral values rather than measured numbers, and the shape answer is limited to the local geometry at each carbon rather than a claim about one fixed conformation.
