The correct common name of the compound CH ₃- CH ( Cl )- CH ₂- CH ₂- CHO is

Step-by-step solution

The given compound is an aldehyde with a straight chain of 5 carbon atoms. The common root name for a 5-carbon aldehyde is valeraldehyde. In common nomenclature, the carbon atom directly adjacent to the carbonyl group is designated as the -carbon, the next is , and the one after that is . Assigning the positions: C1: carbonyl carbon ( - CHO ) C2: -carbon ( - CH ₂- ) C3: -carbon ( - CH ₂- ) C4: -carbon ( - CH ( Cl )- ) C5: -carbon ( - CH ₃ ) The chlorine atom is attached to the -carbon. Combining the substituent pos
