it reduces aldehyde into primary alcohol n ketone into secondary alcoholZaqZainab
sister can you tell me that does NaBH4 reduces CHO group?

ZaqZainab
sister can you tell me that does NaBH4 reduces CHO group?
it reduces aldehyde into primary alcohol n ketone into secondary alcohol
sorry i meant does H2 and Ni catalyst reduce CHO?Aldehyde to primary Alcohol
Ketones to Secondary alcohol
CH3CH=CHCHOsorry i meant does H2 and Ni catalyst reduce CHO?
Aren't these the conditions for hydrogenation :/sorry i meant does H2 and Ni catalyst reduce CHO?
Yes, both NaBH4 and H2 with nickel as catalyst.sorry i meant does H2 and Ni catalyst reduce CHO?
CH3CH=CHCHO
140 degree + Ni + H2
what will be result?
CH3CH2CH2CHO or CH3CH2CH2CH2OH
yes... these reagents cnvert alkenes into alkanes n carbonyl compounds into alcohol..sorry i meant does H2 and Ni catalyst reduce CHO?
we say the same thing at same timeyes... these reagents cnvert alkenes into alkanes n carbonyl compounds into alcohol..
where as NiBH4 n LiALH4 can only reduce carbonyl compounds
robinhoodmustafa plzzelimination, reduction or hydrolysis or dehydration!!! i need differences between them en reagents used for these reactions
no.. i said that H2 n Ni reduces both alkenes n carbonyl compounds... n u said that they only reduce alkenes...we say the same thing at same time
He said at the same time not thingno.. i said that H2 n Ni reduces both alkenes n carbonyl compounds... n u said that they only reduce alkenes...
he said that: the same thing at the same timeHe said at the same time not thing
oh XDhe said that: the same thing at the same time
its ok... first i thought that i've made mistakehttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s09_qp_2.pdf
Second Variant
Q5
I didn't understand the question itself is it saying 2CH3CHO Or just CH3CHO
And i need help for part a)
oh XD
Sorry, when i read fast i make mistakes.
Oh yes yes.no.. i said that H2 n Ni reduces both alkenes n carbonyl compounds... n u said that they only reduce alkenes...
dun u think!! elimination is more than substitution u told :'|Elimination. A functional groups gets replaced by another group + creating water
Reduction is gain of hydrogen by the removal of oxygen
Oxidation is gain of oxygen and loss of Hydrogen
(OIL-RIG)
Hydrolysis bond formation with the elimination of a water molecule
and dehydration is pulling back h20 from the compound (H and OH) -Removing H
Elimation. Can be Halogens (I , Br , Cl)
Reduction. NABH4 . LiAlH4 , Zn, H2
Oxidation : Kmno4 , K2Cr2O7 , H2so4
Hyrdrolysis. Agno3 , H20
Dehyrdration : H3PO4 , H2so4
