Neutral divalent carbon species released as reaction intermediate in reaction of ethylene is
Options
(a) carbocation
(b) carbene
(c) carbanion
(d) free radical
Correct Answer:
carbene
Explanation:
Carbocation is the +ve charged carbon species. e.g. ⁺CH₃, ⁺C₂H₅.
Carbanion is the -ve charged carbon species. e.g. ⁻CH₃, ⁻C₂H₅.
Free radical is the trivalent neutral carbon species with an electron. e.g. CH₃, C₂H₅. Carbene is the divalent neutral carbon species with two free electrons. This is two types, such as single and triplet. e.g. :CH₂(triplet), :CH₂(singlet).
