In which species are all the carbon atoms considered to be sp2 hybridized? - Sri Chaitanya Infinity Learn Best Online Courses for NCERT Solutions, CBSE, ICSE, JEE, NEET, Olympiad and Class 6 to 12

A
$C_{2} H_{2}$
B
$C_{2} H_{4}$
C
$C_{3} H_{8}$
D
$C_{4} H_{10}$

Solution:

Due to the participation of all s and p orbitals in bond formation, alkanes have ${sp}^{3}$ hybridized carbon. Alkenes have ${sp}^{2}$ hybridized carbon with a double bond because bond formation only involves one s and two p orbitals. A p-orbital is empty in one.
As only one s and one p orbital participate in the creation of the bond, alkynes have sp hybridized carbon with triple bonds. Two p-orbital is vacant at this time.

In which species are all the carbon atoms considered to be ${sp}^{2}$ hybridized?
