Carbonyl
Hyperconjugation
Hyperconjugation is the delocalization of electrons from a sigma bond (usually C-H or C-C) to an adjacent empty or partially filled p-orbital or π-system. This interaction stabilizes the molecule by spreading out electron density.
Inductive effect
The inductive effect help stabilise carbocations by dispersing positive charge through sigma bonds, especially when there are nearby electropositive or electronegative atoms
Rearrangments
Carbocation
Pinacol
A methyl group migrates to form a more stable carbocation, which deprotonates to yield a stable product

Reference material used
TMS, Tetramethylsilane, (CH3)4Si
Used because it has a low boiling point and non-polar, meaning it can be easily removed
Used because it is chemically inert, so does not react with other samples
