I have a phrase that reads: > Section 8.01, entitled "Polar Bonding in Basic Organic Compounds," > provides, in pertinent part, that due to the slight electro-negative > bias of fluorine, the carbon-fluorine bond has an electronegativity > that slightly favors the Fluorine pole. The first part of the sentence is what I'm concerned with. Should I remove the commas separating "in pertinent part"? What's the grammatical justification?
