(a)
Interpretation:
The systematic name given should be checked that whether it is correct or not and also the correct name should be given if in case the given name is wrong.
Concept Introduction:
NOMENCLATURE RULES:
- 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.
