Organic Chemistry

Question 1

which functional groups undergo electrophilic addition?

Answer 1

alkenes –> alkanes / halogenoalkanes / alcohols

Question 2

R+C for electrophilic addition of alkene?

Answer 2

Br2(l) or Br2 in CCl4 –> add 2 Br to the compound
Br2 (aq) –> Br and OH
HBr (g) –> H and Br
conc H2SO4, followed by H2O (l), warm –> H and OH

Question 3

which functional groups undergo elimination?

Answer 3

halogenoalkanes / alkanes –> alkenes

alcohols –> alkenes

Question 4

R+C for elimination of alkanes?

Answer 4

ethanolic KOH (or NaOH), heat

Question 5

R+C for elimination of alcohols?

Answer 5

excess conc. H2SO4, 170°C
