MCQ
The $ IUPAC$ name of $C{H_3}C \equiv CCH{(C{H_3})_2}$ is
- ✓$4-$ methyl $-2-$ pentyne
- B$4, 4-$ dimethyl $-2-$ butyne
- CMethyl isopropyl acetylene
- D$2-$ methyl $-4-$ pentyne
Now, we start numbering from the leftmost carbon as by doing that, the triple bond will be on $2^{nd}$ carbon.
Hence, the name of the compound will be $4$ methyl-$2$-pentyne as there are $5$ carbons on the parent chain.
