Haloalkanes and Haloarenes

Finkelstein Reaction

Halogen exchange to prepare alkyl iodides

R–X + NaI → R–I + NaX

X = Cl, Br

Swarts Reaction

Halogen exchange to prepare alkyl fluorides

H3C–Br → H3C–F + AgBr

Sandmeyer’s Reaction

Sandmeyer's Reaction

Order of Reactivity of Alkyl Halides for SN1 and SN2 Reactions

SN1 – 3° > 2° > 1°

SN2 – 1° > 2° > 3°

For a given alkyl group (R–X)

R–I > R–Br > R–Cl >> R–F

Chirality

Molecules are non-superimposable on their mirror image

Optically active

An asymmetric or chiral carbon contains 4 different groups attached to it

Enantiomers

Stereoisomers that are mirror images and are non-superimposable

They have identical physical properties

They differ with respect to the rotation of plane polarised light, i.e. dextrorotatory and laevorotatory

Racemic Mixture

It is a mixture containing two enantiomers in an equal amount

zero optical rotation

Wurtz Reaction

2RX + 2Na → RR + 2NaX

Friedel-Crafts Reaction

Friedel-Crafts Reaction
