Consider the reactions sequence:
CH3−CH2−C≡CH→NaX→CH3−IProduct\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{C} \equiv \mathrm{CH} \xrightarrow{\mathrm{Na}} \mathrm{X} \xrightarrow{\mathrm{CH}_3-\mathrm{I}} \text {Product}
Final product in the above reaction sequence is:
View answer and explanation
Correct option: B
CH3−CH2−C≡C−CH3\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{C} \equiv \mathrm{C}-\mathrm{CH}_3
Option B (CH3−CH2−C≡C−CH3\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{C} \equiv \mathrm{C}-\mathrm{CH}_3) is correct because the reaction sequence involves deprotonation of the terminal alkyne followed by alkylation with methyl iodide.
