Nitroethane and Ethyl nitrite have same chemical formulae. But What is difference between them? Do they show same chemical properties?

answered-by-expert Expert Answer

Boiling Point:

Boiling point of ethyl nitrite is 170C

Boiling point of Nitroethane is 1150C.

Reduction with metal and acid:

Ethyl nitrite gives alcohol+ hydroxyl amine or NH3

C2H5ONO  +  4H  →   C2H5OH +   NH2OH

Nitroethane gives corresponding primary amine.

C2H5NO2 +  6H  →     C2H5NH2 +   2H2O

Action on NaOH:

Ethyl nitrite is readily hydrolysed to give corresponding alcohol and sodium nitrite.

C2H5ONO +  NaOH   →          C2H5OH  + NaNO2

Nitroethane is not decomposed and alcohols are not formed.

Action on nitrous acid:

Nitrous acid has no action ethyl nitrite.

Nitro ethane when reacts with nitrous acid forms nitrolic acid which dissolves in alkali to give red solution.

sir/madam, this doubt will be lenghty. request peace reading. the doubt is w.r.t chapter Amines; to be specific it is w.r.t basicity of amines. in the topic of the comparision of the basic character of alkylamines with ammonia,  the order of basicity of amines is tertiary> secondary> primary in gaseous phase, only due to the +I effect. in gasous phase only +I effect is shown? also in the aqueous phase, the disturbancy in the order of basicity is due to the sum of effects of +I effect, solvation effect and steric hindrance? the order of the stability of the following in aqueous phase: +I effect: tertiary> secondary> primary solvation: primary > secondary > tertiary steric hindrance: primary > secondary > tertiary so does it means that +I is effected in both gaseous and aqueous phase but solvation and steric hindrance are effected only in aqueous phase? also sir there is an order of basicity when R= CH3 group and when R= C2H5 group: R= CH3: secondary> primary> tertiary R= C2H5: secondary> tertiary> primary so sir can we generalise the order that: when R=CH3 group, the order of basicity: secondary> primary> tertiary and when R> CH3 group, the order of basicity: secondary> tertiary> primary

sir/ madam, is it true that if no of bonds in an atom increases then the atom acquires a positive charge on it and when it loses one bond it acquires a negative charge on it ? why does it happen so?
