Question

$C_2-C_3$ sigma single bond in vinyl acetylene $C{H}_2=CH-C\equiv CH$ is due to overlapping of:

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

Answer 1

The correct option is D $s{p}^2-sp$

Here,
$C{H}_2=CH-C\equiv CH$
$s{p}^{2}s{p}^{2}spsp$

So $C_2-C_3$ bond is in between $s{p}^2-sp$ hybridised carbon.
