CHOCHO EthanalCH2(CHO)CH(CHO)CH2CHO= propane 123 carbaldehyde.This so because all the three alde. Groups are not coming in parent chain by any means. So we have to consider all the three as side chain as we can`t prefer any between them because all are same. So when aldehyde group is taken as side chain it is written as carbaldehyde. And so the name.
