Answers
Answer:
1)2,6 dietane heptane
2)etyal propine
3)2-phenayl ethanol
4)3-methaylphenol
I have attached all the IUPAC names in the document below.
I hope that you will go through them and I hope that they would be helpful.
A) =>Redraw the open uncondensed diagram and see how the longest carbon chain is 9 atoms, so root word is non .
So, IUPAC name is: 3,7-Dimethylnonane
B) Here, amine is given more preference than alkene, so the suffix has to be
-amine and not -ene.
So, IUPAC name is: 2-Methyl-3-penten-1-amine
C)Here, it is observed that a double and a triple bond are present.
=>For this, the IUPAC has said that if both can get the same number, numbering always starts from the double bond. So, the alkene is where numbering starts from, but the suffix will still be -yne and not -ene.
=>The longest carbon chain will be six, so root word is hex.
So, the IUPAC name is 4-Methylhex-1-en-5-yne
D) =>Draw the complete structure neatly first for this one.
=>It is clearly visible that this compound is the derivative of a carboxylic acid. It was made when ethyl group replaced the hydrogen in the carboxyl group.
=>So it is an ester and has the suffix -oate .
=>The type of carboxylic acid it was derived from was propanoic acid.
=>So, the IUPAC name is Ethyl propanoate
E) => This compound has a benzene ring attached to it.
=> Redraw the structure neatly and completely to understand it better.
=>In this compound, hydroxyl group is also attached, there exist two carbon atoms between the benzene ring and the hydroxyl group.
=>So, it will obviously not be phenol.
=>Numbering begins from the carbon attached to the hydroxyl group.
=>The phenyl group is attached to the 2nd carbon atom.
=> So, the IUPAC name is 2-Phenylethan-1-ol
(F) =>Both a hydroxyl group and a methyl are attached to a benzene ring.
=>We know that the compound will be phenol and not a toluene.
=>Numbering for all phenols begins from the hydroxyl group.
So, the IUPAC name is 3-Methylphenol
