Need the structural (stick) formula for these molecules:

N-propylbutanamide

4-methylhexan-2-ol

butan-1 4-dioic acid

methyl methylamine

Need to name these molecules:

1)
O
||
CH3 CH2 CH2 C-NH CH3

2)

CH3
|
CH3 CH2 N CH3

3)

CH3COBr
O
||
CH3 C--OCH2CH3

3)

CH2OH
|
CHOH
|
CH2OH

Thanks

What have you got so far?

[GaryGlobetrotter]

I've attempted these but I know they're incorrect

[EierVonSatan]

So? Your mistakes are important in learning how to rectify them

N-propylbutanamide

N-propyl = 3 carbon chain attached to a nitrogen
butan = 4 carbon chain
amide = err amide

4-methylhexan-2-ol

4-methyl = a CH₃ group attached at position 4
hexan = 6 carbon chain
2-ol = hydroxy group in the 2 position

that help at all?

Thanks. Is this right for N-propylbutanamide?

I explained that badly, sorry

Butanamide is CH₃CH₂CH₂CONH₂

The N-propyl bit replaces one of the N-H's above to become:

CH₃CH₂CH₂CONHCH₂CH₂CH₃

http://i50.tinypic.com/2ed8vo8.jpg 4-methylhexan-2-ol?

butan-1 4-dioic acid

butan = 4 carbon chain

1,4-dioc acid = carboxylic acids at the 1 and 4 positions

methyl methylamine

Not sure if that's a valid name for something, do you mean dimethylamine?

[GaryGlobetrotter]

Thanks again.

I'll ask my teacher about the 'methyl methylamine'.

Could you provide me with some of your guidance in naming the structures please?

[GaryGlobetrotter]

Ahh, the positions messed up! -_-

Here they are: http://i45.tinypic.com/10xfpt3.jpg

I can only make out the last one from your drawings

It has a 3 carbon chain => propan
it has 3 alcohol groups => triol

As the OH's are on a different carbon each: propan-1,2,3-triol is the name

edit: ah okay

e) longest chain = ethan
it's an amine
there are 2 methyl groups attached to the nitrogen

f) longest chain = ethan
COBr = acyl bromide

g) it's an ester with two carbon chains, which are both ethan

Ok, so...

e) N-2methylethanamine

f) Acylethylbromide

g) Ethyl ethanoate

?

[EierVonSatan]

e) N-2methylethanamine

Close. N,N-dimethylethanamine

The two N's indicate position (like numbers do) the di means there are two of them

f) Acylethylbromide

Ethanoyl bromide

g) Ethyl ethanoate

Ethanoyl bromide

Thanks for all of your help today. Rep given.
