Question

what is it's icpuc name?​

Answer 1

=> You can see that a Hydroxyl group is present, so it is an alcohol and has the suffix "-ol".

=> We will number the longest carbon chain from the left side of the molecule so that the Hydroxyl group gets the lowest possible numbering.

=> So, the longest carbon chain consists of six carbon atoms. So, the root word will be "hex" .

=> The carbon atom attached to the hydroxyl group gets the number 3, the double bond gets the number 2 , the Chlorine atom gets the number 4 and lastly, the triple bond gets the number 5 .

=> So, the IUPAC name is 4-Chlorohex-2-en-5-yn-3-ol
