Question

The hybridisation of carbon atoms in C C single bond of above compound is:

• A. $s{p}^3-s{p}^3$
• B. $s{p}^3-s{p}^2$
• C. $s{p}^2-s{p}^2$
• D. $sp-s{p}^2$

Answer 1

Answer: (D)

$sp-s{p}^2$

Out of two carbon one which is surrounded by CH on both side has two high electron density region around it thus it shows sp hybridization.

The carbon which is surronunded by C, H and $C{H}_2$ have 3 high electron density region thus it shows $s{p}^2$ hybridization.
