Question

How to convert bromoethane to methanoic acid?
(with chemical equation)

Answer 1

Can you write their formulae ?

Answer 2

bromoethane - CH3CH2BR

Answer 3

right . ^^

Answer 4

methanoic acid - HCOOH

Answer 5

correct .

Answer 6

can you tell me your grade ???

Answer 7

SO what's the mechanism in converting bromoethane to methanoic acid?

Answer 8

Pre-university

Answer 9

I don't think so its a single step reaction . I mean we can't directly convert bromoethane to methanoic acid

Answer 10

Yes we can"t convert it directly. So can you explain to me the steps of the conversion?

Answer 11

Plus providing the chemical equations?

Answer 12

wait Its take time . :)

Answer 13

It's okay.

Answer 14

ok first we convert bromoethane to ethyl alcohol

Answer 15

\[CH3CH2Br + KOH \rightarrow CH3CH2OH + KBr (S _{N}2 reaction)\]

Answer 16

Now ethyl alcohol to methyl alcohol

Answer 17

okay then?

Answer 18

Ethanol + {O} ---> Ethanal + H2O (Catalyst are K2Cr2O7 + H2SO4 )
Ethanal + {O} ---> Ethanoic acid ( Catalyst are same )
Ethanic acid + NaOH ---> CH3COONa + H2O
CH3COONa + NaOH ---> CH4 + Na2CO3 (Catalyst is CaO )

Answer 19

CH4 + {O} --> CH3OH ( Cu 400 C and 200 atm)

Answer 20

last step
CH3OH + {O} --> HCHO + H2O ( Catalyst are K2Cr2O7 + H2SO4)
HCHO + {O} --> HCOOH

Answer 21

CH3CH2OH + CONCENTRATED H2SO4 ------> CH2=CH2
CH2=CH2 + O3 + Zn + H2O ----> CH2OH + ALKALINE KMnO4 ---> CH3COOH

Answer 22

SORRY IT IS NOT CH3COOH(IN THE LAST REACTION), IT IS HCOOH.

Answer 23

there are many ways to convert into Formic acid . I choose this one @amirulzamel

Answer 24

Hey you there ???????????

Answer 25

ohhh okay okay. thank you both sarah and rohitkhanna

Answer 26

lol yw AND @Rohitkhanna its HCHO not CH2OH

Answer 27

ya.that one too.thanx for the correction @sarah786 .

Answer 28
