A skeletal chemical structure of a molecule with a carboxylic acid group on the left and an amine group on the right, connected by a zigzag carbon chain.

Draw an isomer of Compound 1, as a structural formula, that has the -NH2 in a different position on the carbon chain and does not contain a chiral carbon atom🔹 Step-by-step guide to drawing the skeletal formula of Compound 1: Draw a zigzag chain of 7 carbon atoms. Each corner or end represents a carbon. Start from the left, moving right. Label the ends: At the left end (carbon 1), attach a carboxylic acid group: A double bond to an O (C=O) A single bond to OH (–OH) This makes a COOH group. Count three carbons along the chain from the COOH end: On carbon 3, attach an NH₂ group sticking off the chain. All other bonds are just CH₂ groups forming the backbone. 🧠 Chiral carbon identification: The third carbon (where NH₂ is attached) is bonded to: An NH₂ group A hydrogen A chain going to the COOH A chain going to the rest of the carbon backbone These four groups are all different → this carbon is chiral.
