Question
CH3−CH2−Br(i)Li−−−−−−−→(ii)CuBr,Δ(A)CH3−Cl−−−−−→Δ(B)
Open in App
Solution
The correct option is A (A)[CH3CH2]⊖2CuLi⨁(B)CH3−CH2−CH3
Ethyl bromide reacts with Li followed by the action of cuprous bromide to form diethyl lithium cuprate (compound A).
Compound (A) on heating with methyl chloride forms n propane (compound B).
CH3−CH2−Br(i)Li−−−−−−−→(ii)CuBr,Δ[CH3CH2]⊖2CuLi⨁(A)CH3−Cl−−−−−→ΔCH3−CH2−CH3(B)
Thus, (A)[CH3CH2]⊖2CuLi⨁(B)CH3−CH2−CH3
Ethyl bromide reacts with Li followed by the action of cuprous bromide to form diethyl lithium cuprate (compound A).
Compound (A) on heating with methyl chloride forms n propane (compound B).
CH3−CH2−Br(i)Li−−−−−−−→(ii)CuBr,Δ[CH3CH2]⊖2CuLi⨁(A)CH3−Cl−−−−−→ΔCH3−CH2−CH3(B)
Thus, (A)[CH3CH2]⊖2CuLi⨁(B)CH3−CH2−CH3
