Problem
A line-angle drawing shows a three-carbon chain in which the central carbon is double-bonded to an oxygen atom; no hydrogen atoms are drawn. What is the molecular formula implied by this drawing? a) b) c) d)Intuitive explanation
This is about reading a line-angle structure and counting atoms carefully. In line-angle drawings, each vertex and line endpoint represents a carbon atom, and hydrogens are implied — you add them so each carbon reaches exactly four bonds. Start by identifying the three carbons and the C=O double bond, then work out how many hydrogens each carbon needs based on its existing bonds. The key is remembering that line-angle drawings are a shorthand: what you don't see drawn is still there.
