Question

Discuss the formation of acetylene molecule using the concept of hybridization
​

Answer 1

Answer:

In the hybrid orbital picture of acetylene, both carbons are sp-hybridized. ... The C-C sigma bond is formed by the overlap of one sp orbital from each of the carbons, while the two C-H sigma bonds are formed by the overlap of the second sp orbital on each carbon with a 1s orbital on a hydrogen

Answer 2

Answer: In the hybrid orbital picture of acetylene, both carbons are sp-hybridized. ... The C-C sigma bond is formed by the overlap of one sp orbital from each of the carbons, while the two C-H sigma bonds are formed by the overlap of the second sp orbital on each carbon with a 1s orbital on a hydrogen.

Explanation:

C2H2 has sp-hybridization and it is explained as the two carbon atoms undergo mixing of one s and one p-orbitals to form two sp-hybridized orbitals and the sp-hybridized orbital of the C-atoms make a C-C sigma bond while the other sp-hybrid orbital of each C-atom overlaps with the s-orbital of one H-atom to form a C-H sigma bond.

All types of Alkane have Sp3 (single bond) hybridization

All types of Alkene have Sp2 (double bond) hybridization

All types of Alkyne have Sp (triple bond) hybridization
