Look for repeating units or parentheses indicating branching. For example, in CH3(CH2)3CH(CH3)2<\/strong>, the main chain is 5 carbons long, with branching on the 4th carbon.<\/li>\n\n\n\n
Parentheses indicate groups attached to the main chain. In CH(CH3)2, the central carbon is bonded to two methyl groups. This should be drawn as branches from that carbon.<\/li>\n\n\n\n
Groups like CO (carbonyl) and CN (nitrile) indicate double bonds to oxygen or triple bonds to nitrogen. For example, CH3CH2COCN<\/strong> has a ketone (carbonyl) attached to a nitrile group.<\/li>\n\n\n\n
Sketch the longest continuous chain or the core structure, then add branches and functional groups.<\/li>\n\n\n\n\n
