Question

Which of the following alkene cannot be prepared by de-amination of $\underset{(n-Butyl)}{n-Bu-N{H}_2}$ with $NaN{O}_2/HCl$?

• A. $1$-butene
• B. Cis-$2$-butene
• C. Trans-$2$-butene
• D. Iso-butene

Answer 1

The correct option is D Iso-butene

$NaN{U}_z+Fd\to NaCl+HN{O}_3$

$2-$ butane has geometrical isomers as $-2-$ butane trans $-2-$ butane
