Question

The maximum number of isomeric alkenes with the molecular formulae $C_4{H}_8$ is:

• A. $2$
• B. $3$
• C. $4$
• D. $5$

Answer 1

The correct option is B $3$

$C_4{H}_8$

Maximum possible=$3$

a) $H_{3}C-H_{2}C-\stackrel{H}{\stackrel{|}{C}}=C{H}_2$

b)$H_{3}C-\stackrel{H}{\stackrel{|}{C}}=\stackrel{H}{\stackrel{|}{C}}-C{H}_3$

c)$H_{3}C-\stackrel{H}{\stackrel{|}{\underset{C{H}_3}{\underset{|}{C}}}}-C{H}_2$
