Common name: No common name
Work Step by Step
There is a methoxy group on cyclohexane. Since the carbon in C=O is not a part of the main chain it's named carbaldehyde. Since there is a methoxy group on the second carbon (first is the one attached to aldehyde) and it's trans to CHO, it is called trans-2-methoxycyclohexanecarbaldehyde.
There is no common name.
