[08.05] which answer provides the correct name for name the following hydrocarbon? (2 points) moving left to right: a hydrocarbon chain made of a methyl group (ch subscript three) single bond carbon triple bond carbon single bond ch bonded to a methyl group (ch subscript three) and a chain including a methelyne group (ch subscript two) single bond methyl group (ch subscript three). 4-ethyl-2-pentyne 4-methyl-2-hexyne 2-heptyne 4-methy-hexane

The rules of IUPAC followed for hydrocarbon are

a)We will first find out the longest chain of carbon in the given organic compound  including triple bond

the root name will be "hex" as number of carbon atoms in longest chain is six.

b)The triple bond will be assigned minimum number locant. the locant will be 2 .

The primary suffix will be "yne"

hence

hex-2-yne

c) we will give locant number to methyl group (present as substituent)

it will be "4"

Thus the completer IUPAC name will be

4-methylhex-2-yne or 4-methyl-2-hexyne [as given in the options]
