Current Question (ID: 10850)

Question:

$\text{The IUPAC name of the above-mentioned compound is:}$

Options:

1. $\text{Pent-1-en-3-yne}$
2. $\text{Pent-1-ene-4-yne}$
3. $\text{Pent-4-yn-1-ene}$
4. $\text{Pent-1-en-4-yne}$ (Correct)

Solution:

$\text{Hint: Double bond gets higher priority}$ $\text{When double bond and triple bond are present at the terminal position then double bond gets higher priority. Numbering should be done in such a way that double bond carbon gets the least position. The numbering must be down from left to right.}$ $\text{For double bond, en is used as a suffix and for a triple bond, yne is used as a suffix. The structure with numbering is given below:}$ $\text{The parent chain contains 5 carbon atoms hence, pent is used. Thus, the name of the compound is pent-1-en-4-yne.}$
