Document Summary
Sn1: 3 alkyl halide r-x , bad nucleophile leaves on its own no backside attack. Breaks double bond adds oh to less substituted side. Acid catalyzed hydration of an alkene: breaks double bond adds to most substituted side, creates a carboncation. Osmulstion of an alkene: oso4 ( the martian that drops oh"s) breaks double bond adds diols to both sides of double bond, they are cis to each other and pushes most hindered side back. Darzens reaction (socal and pyr) socl2 and pyr. Primary and secondary alcohols only: reacts with socl2 and pyr to remove the oh and replace it with cl (always) . The pyr is protonated becomes hpry and and socl2 becomes so2 +cl- but that"s junk. *basically remove the oh and add cl in backside attac , essentially and sn2 reaction. On a tertiary alcohol: reacts with hcl and follows sn1 but it has to be sp3.
