Vedclass · Answer

(B) To name the compound $CH_3-CH(CH_3)-CH(CH_3)-C\equiv C-CH_3$ according to $IUPAC$ rules:$1$. Identify the longest carbon chain containing the triple bond. The chain has $6$ carbons,so the parent alkane is $hexane$.$2$. Number the chain from the end that gives the triple bond the lowest possible locant. Numbering from right to left,the triple bond starts at carbon $2$.$3$. Identify the substituents: there are two methyl groups at positions $4$ and $5$.$4$. Combining these,the name is $4,5-$dimethyl-$2-$hexyne.

Choose the correct $IUPAC$ name of the compound $CH_3-CH(CH_3)-CH(CH_3)-C\equiv C-CH_3$.
