1.	The C-O bond in carbonyls is polarised, and hence the carbonyl carbon and carbonyl oxygen act as _________ and ________ respectively.(a) electrophile; nucleophile(b) nucleophile; electrophile(c) Lewis base; Lewis acid(d) electrophile; Lewis acidThis question was posed to me by my college professor while I was bunking the class.My enquiry is from Nomenclature and Structure of Carbonyl Groups in division Aldehydes, Ketones and Carboxylic Acids of Chemistry – Class 12
Answer» CORRECT answer is (a) electrophile; nucleophile Easiest explanation: The polarity of the C-O bond is due to the HIGHER electronegativity of O than C. This MEANS that OXYGEN is a nucleophilic centre and CARBON is an electron seeking centre.
