A Map of School Conversions

Chemistry · Class 11

Standard explanation

Alkene --H2/Ni--> alkane. Alkene --HBr--> haloalkane. Alkene --steam/H+--> alcohol. Haloalkane --KOH aq--> alcohol. Haloalkane --KOH alc--> alkene. Alcohol --dichromate--> aldehyde/ketone/acid. Alcohol --conc H2SO4--> alkene. Acid + alcohol --H2SO4--> ester. Haloalkane --CN- --> nitrile --hydrolyse--> acid (extra carbon). Meaning: draw the map, then pick a path of two boxes. Alkene -> halogenoalka

Key points

each arrow is a named reagent
CN- adds a carbon
hydrate then oxidise

A MAP OF SCHOOL CONVERSIONS: Alkene --H2/Ni--> alkane.
1. C=C BOX: In: dehydration or elimination.
2. OH / C=O / COOH: Ox up the hill.
WHAT — A MAP OF SCHOOL CONVERSIONS: Alkene --H2/Ni--> alkane. Alkene --HBr--> haloalkane. Alkene --steam/H+--> alcohol. Haloalkane --KOH
