A) 3-ethyl pentane
B) 2-ethyl pentane
C) 3-methyl hexane
D) 2-methyl hexane
E) n-heptane
Correct Answer: E
Solution :
When lithium dipentyl cuparate reacts with ethyl bromide, it will give n-heptane. This reaction is called Corey-House reaction. \[{{(C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}})}_{2}}CuLi+C{{H}_{3}}C{{H}_{2}}Br\] \[\xrightarrow[{}]{dryether}\underset{n-heptane}{\mathop{C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}C{{H}_{3}}}}\,\] \[+C{{H}_{3}}C{{H}_{2}}Cu+LiBr\]You need to login to perform this action.
