Question

The hybridisation of carbon atoms in $C-C$ single bond of $HC\equiv C-CH=C{H}_2$ is:

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

Answer 1

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

The hybridisation of carbon atoms in $C-C$ single bond of $HC\equiv C-CH=C{H}_2$ is $sp-s{p}^2$. One $C$ atom is bonded to another $C$ atom by a triple bond and is $sp$ hybridised. Other $C$ atom is attached to another $C$ by a double bond and is $s{p}^2$ hybridised.
