Consider reactions A through F . Those carbon atoms undergoing change , as part of a functional group , are marked as `C^(12) , C^(14)` or starred . In the cases shown , each carbon atom has either been reduced or oxidized . Your job is to identify the change in oxidation state that has occured for each of the marked carbon .

Text Solution

Verified by Experts

The correct Answer is:
A : both are oxidized ; B : `C^(12)` is reduced , `C^(14)` is oxidized ; C : reduced ; D : oxidized E : `C^(12)` is reduced , `C^(14)` is oxidized ; F : `C^(14)` is oxidized
A : both are oxidized , B : `C^(12)` is reduced , `C^(14)` is oxidized , C: reduced , D: oxidized
E : `C^(12)` is reduced , `C^(14)` is oxidized , `F: C^(12)` is reduced , `C^(14)` is oxidized

Assertion: C_(3)O_(2) has linear structure. Reason: Each carbon atom in C_(3)O_(2) in sp -hydridized.

Borane is an electron deficient compound. It has only six valence eletons, so the boron atom lacks an octet. Acquiring an octet is the driving force for the unusual bonding structure found in boron compounds. As an electron deficient compound, BH_(3) is a strong electrophile, capable of adding to a double bond. This hydroboration of double bond is though to oC Cur in one step, with the boron atom adding to the less highly substituted end of the double bond. In transition state, the boron atom withdraws electrons from the pi bond and the carbon at theother end of the double bond acquires a partial positive charge. This positive charge is more stable on the more highly subsituted carbon atom. The second step is the oxidation of boron atom, removing it from carbon and replacing it with hydroxyl group by using H_(2)O_(2)//OH^(bar(..)) . The simultaneous addition of boron and hydrogen to the double bond leads to a syn addition. Oxidation of the trialkyl borane replaces boron with a hydroxyl group in the same stereochemical position. Thus, hydroboration of alkenen is an example of steropecific reaction, in which different steroisomers of starting compounds react to give different steroisomers of the product.

Ethylene molecules is formed as a result of sp^(2) hybridisation of carbon. Each carbon atom is excited state undergo sp^(2) hybridisation giving rise to three hybrid orbitals each. These hybrid orbtals lie in the xy plane while the fourth unhybridised orbital lies at right angles to the hybridised orbitals. in the overlap ethylene two hybrid orbitals, i.e., one from each carbon atom from a sigma bond by head on overlap while the remaining overlap with hydrogen atoms. the unhybridised p-orbitals undergo sidewise overlap to from a pi -bonds Ground state of carbon atom Excited state of carbon atom The molecules of ethylene is planar sp^(2) hybridised 'C' atoms are present in ethelene are
