Question

Is this correct?

The structure of aspirin is given below. What is the hybridization of the carbon atom that's bonded to three hydrogens? sp sp^2 sp^3 sp^3d sp^3d^2 What is the hybridization of the other carbon atom? sp sp^2 sp^3 sp^3d sp^3d^2 How does valence bond theory describe the bonding of the C = O bonds? One sigma between hybrid orbitals, one pi between p orbitals One pi between hybrid orbitals, one sigma between p orbitals One sigma and one pi, both between p orbitals Two pi bonds between two sets of hybrid orbitals sigma and one pi, both between hybrid orbitals Two sigma bonds between two sets of p orbitals

Explanation / Answer

a) When carbon is bonded to four other atoms (with no lone electron pairs or double bond), the hybridization is sp3

hybrbridization of carbon atom in which 3 hydrogen bonded is SP3

2) A carbon atom bound to three atoms (two single bonds, one double bond) is sp2 hybridized so 2nd case carbon atom double bonded

3) electronic configurations of carbon and oxygen:

C: 1s2 2s2 2p2
O: 1s2 2s2 2p4

Thus, the carbon has 4 valence electrons and oxygen has 6 valence electrons. The s and p atomic orbitals are available for chemical bonding. The two p hybrid orbitals of central carbon overlaps with one 2p orbital from oxygen atoms to from the one C-O sbonds. carbon overlap with a p orbital of oxygen atoms forming one pi bonds, and one sigma bond.
