Concept explainers
(a)
Interpretation:
The given systematic names should be checked and have to be corrected if the name is wrong.
Concept Introduction:
NOMENCLATURE RULES:
- The first step is to find out the parent chain of the hydrocarbon. Parent chain should contain maximum number of multiple bonds, maximum number of substituents of the
functional group which is used as main suffix. - Other functional group, if any, should be identified and name it as prefix.
- Numbering should be done in such a way as to get the lowest number for suffix functional group, multiple bonds.
- The punctuation used to separate numbers is commas and hyphen is used to separate a number and alphabet.
- If the ‘ane’ ending of the
alkane is replaced by ‘yne’ ending, the name of alkyne is obtained. - Select the longest chain which contains the triple bond in such a way to get lowest value for the functional group.
- Two types of
alkynes will be there according to the position of triple bond. Terminal alkyne is the one which contain triple bond at the end of the chain and internal alkyne is the one which contain triple bond not at the end but present in any other positions in the chain. - When the counting is done from either sides of triple bond in a compound which contain same number for the functional group suffix, the correct name will be the one which have lowest substituent number. In the case of more than one substituent, alphabetical order should be followed.
Skeletal structure: When the atoms bonded in a compound is drawn in a series it can be called as a skeletal structure. In the skeletal structure, we can show the branches, chains, rings or any other hetero atom other than carbon or hydrogen.
Condensed structure: In the condensed structure, atoms or group of atoms are expressed in a line. But it does not contain any vertical bonds and also the horizontal single bonds.

The given systematic names should be checked and have to be corrected if the name is wrong.

- These are synthesis questions. You need to show how the starting material can be converted into the product(s) shown. You may use any reactions we have learned. Show all the reagents you need. Show each molecule synthesized along the way and be sure to pay attention to the regiochemistry and stereochemistry preferences for each reaction.
