Addition Reactions (Leaving Cert Chemistry): Flashcards

Two molecules combine across a double bond

Double bonds (C=C)

Dihalogenated products

Becomes polarised ($\delta^+$ and $\delta^-$)

Act as nucleophile, attack positive halogen

Heterolytic fission

Carbocation or cyclic chloronium ion

Cyclic chloronium ion

1,2-dichloroethane

2-chloroethanol

HI > HBr > HCl > HF

Weakest H-X bond, easiest to break

No, all atoms add on
