WHAT IS HYBRIDISATION OF C2H2 WITH DIAGRAM
Dear student!
The acetylene (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.
Now, the two p-orbitals of each C-atom remained free , which undergo sideways overlapping and forms two C-C pi bonds so that the C-and C atoms have three bonds and it is considered as teh first member of alkyne groups.
The hybridization is represented as:
