Quaternary Ammonium Salts (AQA A-Level Chemistry): Flashcards

All 4 H in $NH_4^+$ replaced by alkyl groups

Positively charged N with no H atoms directly attached

Tetraethylammonium bromide

Low - multiple substitutions give mixture of products

All 4 H atoms already replaced by alkyl groups

Full positive charge ($N^+$)

Hair conditioners, fabric softeners

Cationic surfactants

Positively charged $N^+$ end

$+$ charge attracts to $-$ surfaces, forms coating
