Solution
The correct option is A a. CH3↷−S−CH3→⊕CH3+⊖SCH3;
b. CH3↷−CN→⊕CH3+⊖CN;
c. ↶CH3−Cu→⊖CH3+⊕Cu
(Cu is more electropositive than C).
a). In the heterolytic cleavage, the carbon atom will bear positive charge and the S atom will bear negative charge.
CH3↷−S−CH3→⊕CH3+⊖SCH3
b). In the heterolytic cleavage, the methyl carbon atom will bear positive charge and the cyanide carbon atom will bear negative charge.
CH3↷−CN→⊕CH3+⊖CN
c). In the heterolytic cleavage, the methyl carbon will bear negative charge and the copper will bear positive charge. This is because Cu is more electropositive than C.↶CH3−Cu→⊖CH3+⊕Cu
Option A is correct.
b. CH3↷−CN→⊕CH3+⊖CN;
c. ↶CH3−Cu→⊖CH3+⊕Cu
(Cu is more electropositive than C).
a). In the heterolytic cleavage, the carbon atom will bear positive charge and the S atom will bear negative charge.
CH3↷−S−CH3→⊕CH3+⊖SCH3
b). In the heterolytic cleavage, the methyl carbon atom will bear positive charge and the cyanide carbon atom will bear negative charge.
CH3↷−CN→⊕CH3+⊖CN
c). In the heterolytic cleavage, the methyl carbon will bear negative charge and the copper will bear positive charge. This is because Cu is more electropositive than C.
↶CH3−Cu→⊖CH3+⊕Cu
Option A is correct.
