Q. In the organic compound
$CH _{2}= CH - CH _{2}- CH _{2}- C \equiv CH$, the pair of hybridised orbitals involved in the formation $C _{2}- C _{3}$ bond is

Organic Chemistry – Some Basic Principles and Techniques

Solution:

The carbon atom in the given compound may be numbered as:
$H_{2}\overset{1}{C} = \overset{2}{C}H-\overset{3}{C}{H_{2}}- \overset{4}{C}H_2 - \overset{5}{C} \equiv \overset{6}{C}H$

Thus, $C_2 - C_3$ are bonded by $sp^2 - sp^3$ hybrid orbitals.
