- What is the formally correct notation of t-Bu, i-Pr, p-NO2, n-Bu, a-HCl . . .
isopropyl: iPr isobutyl: iBu sec -butyl: s -Bu tert -butyl: t -Bu However, the recommends different abbreviations: isopropyl: i -Pr isobutyl: i -Bu sec -butyl: sec -Bu tert -butyl: t -Bu Furthermore, authors may create their own abbreviations, but any abbreviations not included in the recommendations shall be defined clearly when they are used
- Is the i prefix for iso- italicised? - Chemistry Stack Exchange

- nomenclature - What are the practices to naming organic chemicals by . . .

- organic chemistry - Newman projections: how to tell which groups are . . .
Well, I think your book is wrong Read the extract: tert tert tert I guess what you're looking for are A-values The higher the A-value, the more "bulky" the group is considered So, the $\ce {-SH}$, $\ce {-Cl}$ and $\ce {-Br}$ groups seem to be less hindering than the $\ce {-iPr}$ group References: A-value, Wikipedia
- Which has higher priority according to Cahn-Ingold-Prelog priority . . .
According to my textbook, vinyl has higher priority than isopropyl, because an atom which is connected by a double bond can be treated as two identical atoms (one of them is just an imaginary atom)
