Question

There is a structure of a six-membered carbon ring with an –O atom double-bonded to the first carbon and a –CH3 group attached to the third and the sixth carbons. Give the IUPAC name.

Answer 1

The IUPAC name for the molecule is 3-methyl-1-oxacyclohex-5-ene.

3-methyl: This indicates a methyl group (CH₃) attached to the third carbon atom of the six-membered ring.

1-oxa: This signifies the presence of an oxygen atom (O) replacing a carbon atom in the ring, specifically at the first position.

cyclohex: This refers to the six-membered carbon ring.

-5-ene: This denotes the double bond between the fifth and sixth carbon atoms of the ring.

Therefore, the complete IUPAC name accurately describes the molecule's structure and functional groups.

The molecule has a methyl group on carbon 3, an oxygen atom replacing carbon 1, a six-membered carbon ring, and a double bond between carbons 5 and 6.

Its IUPAC name is 3-methyl-1-oxacyclohex-5-ene.
