Predict the hybridization of each carbon in the molecule of the organic compound given below. Also indicate the total number of sigma and pi bonds in this molecule.
In the given structure, two carbon atoms are sp hybridized and linked through triple bond, two carbon atoms are sp2 hybridized and linked through double bonds to O atoms and one is sp3 hybridized and that is linked to two C atoms through single bonds and to two H atoms through single bonds, hence, there are total 5 carbon atoms.
Therefore it is clear that in the molecule, there are 11 bonds and 4 bonds.
