Question

Which of the following molecules represents the order of hybridisation $s{p}^2$, $s{p}^2$, $sp$, $sp$ from left to right?

• A. ${\mathrm{CH}}_2=\mathrm{CH}-\mathrm{CH}={\mathrm{CH}}_2$
• B. ${\mathrm{CH}}_2=\mathrm{CH}-C\equiv \mathrm{CH}$
• C. $\mathrm{CH}\equiv C-C\equiv \mathrm{CH}$
• D. ${\mathrm{CH}}_3-\mathrm{CH}=\mathrm{CH}-{\mathrm{CH}}_3$

Answer 1

The correct option is B ${\mathrm{CH}}_2=\mathrm{CH}-C\equiv \mathrm{CH}$

Number of orbitals required for hybridization = Number of $\sigma$-bonds around each carbon atom.
