Question

$H_{3}C-CH=\stackrel{H_{3}C}{\stackrel{|}{C}}-C{H}_2-C{H}_3$

Identify the product formed when the following alkene is hydrogenated with hydrogen in the presence of nickel as catalyst

• A. $H_{3}C-C{H}_2-\stackrel{H_{3}C}{\stackrel{|}{C}}H-C{H}_2-C{H}_3$
• B. $H_{3}C-C{H}_2-\stackrel{H_{3}C}{\stackrel{|}{C}}H-C{H}_3$
• C. $H_{3}C-C{H}_2-\underset{C{H}_3}{\underset{|}{\stackrel{H_{3}C}{\stackrel{|}{C}}}}-C{H}_3$
• D. $H_{3}C-C{H}_2-\stackrel{H_{3}C}{\stackrel{|}{C}}H-C\equiv CH$

Answer 1

The correct option is A $H_{3}C-C{H}_2-\stackrel{H_{3}C}{\stackrel{|}{C}}H-C{H}_2-C{H}_3$

When hydrogenation of the given alkene takes place in presence of Ni as a catalyst, then addition of hydrogen takes place across the double bond leading to formation of corresponding alkane.

Thus, The compound in option A will be produced as a product.
