N and N,N in organic compounds?

Question

N-BUTYL AMINE is:
CH3-CH2-CH-CH3-NH2
Here,why "N" is used?
sometimes we write "(N,N)" example-( 2-(N,N-dimethyl amino)butane)in chemical names.
In writng names of organic compound,why and where N and N,N is used.please explain me.

Answer 1

Remember, that usually little n- refers to hydrocarbon residua and shows that they have flat carbon chains (for example, your formula of n-butylamine, but here must be SMALL n-). We write large N- or N,N- when it's necessary to show that there is something that substitutes one or two hydrogen atoms in amino group, here large N symbolizes nitrogen. So 2-(N,N-dimethyl amino)butane would be CH3-CH[N(CH3)2]-CH2-CH3,
and N,N - dimethylanilin formula is Ph-N(CH3)2.

Answer 2

lester misunderstood your question
butyl anmine is CH3-CH2-CH-CH3-NH2
if one h of NH2 is replace by CH3 it is called
N methyl butanamine if bth hs are replaced it is called
N,N dimethyl butanamine (iupac )
or 2-(N,N-dimethyl amino)butane
so basicly if the h is replaced we do that

Answer 3

the N means 'normal' to differentiate between sec and tert-butylamine. It simply helps to confirm that you mean the straight chain version of butylamine rather than any of its isomers. The same is true for:

n-pentane, n-hexane etc etc.

It is more usual to use "n" rather than "N" though.

Answer 4

u r getin confused!!!n b4 the formula is for normal chain compounds and n in middle of chain is for nitrogen...consult ur teachers for detailed xplaination

Answer 5

WOW!, it has been too much time. Does it can be related to molecules orientation and bonding?
