Question

$C{H}_3\equiv CH\underset{Ether}{\overset{C{H}_{3}MgBr}{\to }}\stackrel{C{H}_{3}COC{H}_3}{\to }\stackrel{C{H}_{3}I}{\to }$

What is the final product?

• A. $(C{H}_3{)}_2\stackrel{OH}{\stackrel{|}{C}-}C\equiv CC{H}_3$
• B. $(C{H}_3{)}_2\stackrel{OH}{\stackrel{|}{C}C}\equiv CC{H}_3$
• C. $C{H}_{3}C\equiv CC{H}_2\stackrel{OMe}{\stackrel{|}{C}H}C{H}_3$
• D. $(C{H}_3{)}_{3}CC\equiv COMgBr$

Answer 1

The correct option is B $(C{H}_3{)}_2\stackrel{OH}{\stackrel{|}{C}C}\equiv CC{H}_3$

The final product of the given reaction is represented by option (B). The reaction is as shown above.
