What is homolytic cleavage of covalent bond? Explain by example |
|
Answer» Solution :In homoltic cleavage, one of the ELECTRONS of the shared pair in a covalent bond goes with each of the bonded atoms. In homolytic cleavage, the movement of a SINGLE electron takes place instead of an electron pair. The single electron movement is shown by .half.headed. (fish hook  ) curved arrow Such cleavage results in the formation of NEUTRAL species (atom or group) which contains an unpaired electron. These species are called FREE radicals. Like carbocations and carbanions, free radicals are also very reactive. A homolytic cleavage can be shown as:  Organic reactions, which proceed by homolytic fission are called free radical or homopolar or nonpolar reactions |
