mechanisms

Question 1

for nucleophilic substituition w ammonia what r the conditions

Answer 1

• dissolved in ethanolic solvent
  XS

Question 2

for nucleophilic substituition w OH- what r the conditions

Answer 2

aqueous
room temp

Question 3

for nucleophilic substituition w CN what r the conditions

Answer 3

WARM
dissolved in ethanolic solvent

Question 4

conditions for elimination of halogenoalkanes

Answer 4

• oh- ethanolic
• heat

Question 5

what does oh- act as in elimination of halogenoalkane

Answer 5

base

Question 6

EA of alkenes w sufuric acid

Answer 6

delta pos on H + delta neg on O in h2so4 - oh bond breaks towards delta neg h2so4

Question 7

cond for acid catalysed elim mechanism (alc to alkene)

Answer 7

warm, under reflux
w conc h2so4/h3po4

Question 8

cond for acid catalysed addition mechanism (alkene to alc)

Answer 8

req high T +P
H+ from H3PO4

Question 9

what is nucleophilic addition for

Answer 9

1. reduction of aldehydes and ketons into 1’/2’ alc
2. carbonyl compounds w KCN + dilute acid -> hydroxynitriles

ALD + KET -> ALC/HYDROXYNITRILES

Question 10

NA of aldehyde -> alc where does the H+ come from

Answer 10

from water/WA or NaBH4

Question 11

N AE is for what

Answer 11

acyl chlorides!!!!
