The primary strength of the Chemsheets answers is their precision. In organic chemistry, being "close" is often wrong. The answers distinguish between dilute and concentrated acids, specify the need for acidified potassium dichromate versus aqueous sodium hydroxide, and highlight when heat is mandatory.
Ethene → Ethanol
$Propene \xrightarrowHBr 2\text-bromopropane \dots$ (Wait, wrong way!) Actually, to get the primary alcohol, we need anti-Markovnikov addition.
