Current Question (ID: 17624)

Question:

$\text{An alkene 'A' on ozonolysis gives a mixture of ethanol and pentan-3-one.}$ $\text{The IUPAC name of 'A' is:}$

Options:

1. $\text{3-Ethylpent-2-ene}$
2. $\text{3-Ethylpent-2-yne}$
3. $\text{2-Ethylpent-3-ene}$
4. $\text{3-Ethylpent-4-yne}$

Solution:

$\text{Step 1:}$ $\text{The reaction of A is as follows:}$ $\text{Ozonolysis:}$ \quad \text{A} \rightarrow \text{Ethanol} + \text{Pentan-3-one}$ $\text{During ozonolysis, an ozonide having a cyclic structure is formed as an intermediate which undergoes cleavage to give the final products.}$ $\text{Ethanol and pentan-3-one are obtained from the intermediate ozonide.}$ $\text{Hence, the expected structure of the ozonide is:}$ $\text{Step 2:}$ $\text{This ozonide is formed as the addition of ozone to 'A'.}$ $\text{The desired structure of 'A' can be obtained by the removal of ozone from the ozonide.}$ $\text{Hence, the structural formula of 'A' is:}$ $\text{The IUPAC name of 'A' is 3-Ethylpent-2-ene.}$
