Question
Which statement correctly correlates ? or ? bonding atoms and their respective bonding orbitals in formaldehyde? aThe oxygen atom (with its 2s orbital) forms a ? bond with one of the three sp2 hybrid orbitals of the carbon atom; the two hydrogen atoms (with their 1s orbitals) each form a ? bond with one of the three sp2 hybrid orbitals of the carbon atom. bThe oxygen atom (with its 2p orbital) forms a ? bond with one of the three sp2 hybrid orbitals of the carbon atom; the two hydrogen atoms (with their 1s orbitals) each form a ? bond with one of the three sp2 hybrid orbitals of the carbon atom. cThe oxygen atom (with its 2p orbital) forms a ? bond with the pz orbital of the carbon atom; the two hydrogen atoms (with their 1s orbitals) each form a ? bond with one of the two sp2 hybrid orbitals of the carbon atom. dThe oxygen atom (with its 2p orbital) forms a ? bond with one of the three sp2 hybrid orbitals of the carbon atom; the two hydrogen atoms (with their 1s orbitals) each form a ? bond with one of the three sp2 hybrid orbitals of the carbon atom. The oxygen atom also forms a ? bond with carbon which involves the 2pz orbitals of oxygen and carbon.Explanation / Answer
The answer is:
D)The oxygen atom (with its 2p orbital) forms a s bond with one of the three sp2 hybrid orbitals of the carbon atom; the two hydrogen atoms (with their 1s orbitals) each form a s bond with one of the three sp2 hybrid orbitals of the carbon atom. The oxygen atom also forms a p bond with carbon which involves the 2pz orbitals of oxygen and carbon.
In formaldehyde (H2C=O):
The C atom is sp2-hybridized.
Each H atom forms a single sigma bond with C (1s bonding with sp2)
The O atom forms a double bond (1 sigma and 1 pi bond) with C (1s bonding with sp2 to give sigma bond and 2pz with 2pz to give the pi bond).
