Why in some reactions oxygen atom is enclosed in parenthesis ? Example: (O)
« on: May 06, 2014, 04:25:08 AM »
Hello'
While going through my chemistry text book I came through the following reaction.
RCH2OH + (O)  :rarrow: RCHO + H2O   
In the above reaction why oxygen atom is enclosed in parenthesis ???

I have often seen an O enclosed in brackets,

(O) stands for nascent oxygen which is highly reactive..

O enclosed in round or square brackets in a chemical eqiation represents an unspecified oxidising agent.
