Question

What is the type of hybridisation of carbon atoms marked with star.

$$\begin{array}{c}\phantom{.....}\mathrm{O}\\ \phantom{.....}||\\ \stackrel{\ast }{\mathrm{C}}\mathrm{H}{\phantom{A}}_2=\mathrm{CH}-\stackrel{\ast }{\mathrm{C}}-\mathrm{O}-\mathrm{H}\end{array}$$

Answer 1

The type of hybridization marked with the star in the given structure is:

$$\begin{array}{c}\phantom{.....}\mathrm{O}\\ \phantom{.....}||\\ \stackrel{\ast }{\mathrm{C}}\underset{\mathrm{Sp}{\phantom{A}}^2}{\mathrm{H}{\phantom{A}}_2}=\mathrm{CH}-\stackrel{\ast }{\underset{\mathrm{Sp}{\phantom{A}}^2}{\mathrm{C}}}-\mathrm{O}-\mathrm{H}\end{array}$$
