Current Question (ID: 21307)

Question:

$\text{The major product in the following reaction is:}$ $\text{CH}_3\text{C} \equiv \text{CH} \xrightarrow{\begin{array}{c} (i) \ \text{DCl} \ (1 \ \text{equiv.}) \\ (ii) \ \text{DI} \end{array}}$

Options:

1. $\text{CH}_3\text{CD(Cl)CHD(I)}$
2. $\text{CH}_3\text{CD}_2\text{CH(Cl)(I)}$
3. $\text{CH}_3\text{CD(I)CHD(Cl)}$
4. $\text{CH}_3\text{C(I)(Cl)CHD}_2$

Solution:

$\text{Hint: The reaction is an example of an electrophilic addition reaction.}$ $\text{When alkyne reacts with DCl or HCl then electrophilic addition reaction takes place.}$ $\text{In the second step again, electrophilic addition reaction takes place and Addition of DI takes place across the double bond.}$ $\text{The reaction is as follows:}$ $\text{CH}_3\text{C} \equiv \text{C-H} \xrightarrow{\text{DCl}} \text{CH}_3\text{C} = \text{CH-D}$ $\xrightarrow{\text{DI}} \text{CH}_3\text{C-CHD}_2$
