Lewis acids are defined as electron pair acceptors. Theirstrength is tied to theirlack of electrons with respect to a noble gas configuration: themore deprived ofelectrons, the stronger. In a research project, the boranesB(OCH3)3, B(SCH3)3and B(SeCH3)3 are used as reagents. Explain why B(OCH3)3 – althoughfeaturingstrongly electronegative oxygen as bonding partner – is,nevertheless, a weakerLewis acid than B(SCH3)3 with less electronegative sulphur asbonding partner!Where would the selenium-based borane rank?
