Easy Practice — Set 2

Quick Recap — Reactions & Reagents

• Alkanes: free-radical halogenation (Cl$_2$/UV); Wurtz ($2RX+2Na$); decarboxylation of sodium salts (soda lime).
• Alkenes: Markovnikov HX addition; anti-Markovnikov HBr (peroxide); hydration; ozonolysis $\to$ carbonyls; Baeyer's $\to$ diol.
• Alkynes: terminal alkyne $+$ ammoniacal $AgNO_3$/$Cu_2Cl_2$ (test); hydration $\to$ carbonyl; acidity increases with s-character (ethyne $>$ ethene $>$ ethane).
• Arenes: electrophilic substitution — nitration, halogenation, sulphonation, Friedel-Crafts; o/p vs m directors.
