Explanation:
2,4-DNP is negative: aldehyde and ketone absent
Chromic acid is negative: alcohol absent.
KMnO4 test negative: alkene absent
The only positive result is for Fe(OH)2.
Nitro group-containing compounds react with ferrous hydroxide to give amine and ferric hydroxide red ppt. Hence given compound contains the nitro group (-NO2).
Answer:
this is not and reaction of acid and base.(CaOCL2)
Explanation:
Ca2, Cl, are base and O is a neutral.
so how can that be a acid and base reaction
Only CH3OH contains convalent bonds. Others are metal. But CH3OH is methanol.
Answer:
False.
Explanation:
From the balanced equation, 1 mole of Mg(OH)2 reacts with 2 moles of HCl.
So for 0.40 moles of Mg(OH)2 we need 2*0.4 = 0.80 moles of HCl.
