Question

Which of the following intermediate is formed during heterolytic cleavage of $C-Cu$ bond in $C{H}_{3}C{H}_{2}Cu$?

• A. $C{H}_{3}C{H}_2^{-}$
• B. $C{H}_{3}C{H}_2^{+}$
• C. $C{u}^{-}$
• D. $C{u}^{+}$

Answer 1

Answer: (A), (D)

The correct options are
A $C{H}_{3}C{H}_2^{-}$
D $C{u}^{+}$

Since metals are always electropositive, the heterolytic cleavage takes place in the following way :


Theory :
Bond Cleavage : Breaking of Covalent bond is known as Bond cleavage.
Organic reaction is the process in which breaking and formation of covalent bonds takes place.
Generalized organic reaction :
$\text{Substrate}+\text{Reagent}⟶\text{Products}$
Which can be further explained as :
$\text{Organic molecule(substrate)}\stackrel{reagent}{⟶}\text{intermediate}⟶\text{Product(s)}$
Where intermediates and by products formed.
Substrate :
The reactant which is being attacked in a chemical reaction.
Reagent :
The reactant which attacks the substrate in a chemical reaction.
