2,2 -dimethylpropane [CH3C(CH3)2CH3

[From: ] [author: ] [Date: 11-11-26] [Hit: ]
Molecular Formula for pentane is C5H12. now for 2,2-dimethylpropane, you have a 3 carbon chain and then 2 methyl groups from the second carbon. the molecular formula for this is also C5H12.Same Molecural Formula,......
When drawing the structural formula can it be drawn in a straight chain like this?
H - C - C - C - C - C - H

With the other hydrogens bonding to the carbons (5 hydrogens above -1 hydrogen to each carbon, 5 hydrogens below- 1 hydrogen to each carbon)
In all other pictures I have seen it not drawn out in a straight chain but is it still correct?
Thanks

No, if you had a 5 Carbon Chain with 3 hydrogens on each end Carbon and then 2 hydrogens on the 3 carbons inbetween, you'd have pentane. Molecular Formula for pentane is C5H12. now for 2,2-dimethylpropane, you have a 3 carbon chain and then 2 methyl groups from the second carbon. the molecular formula for this is also C5H12.

Same Molecural Formula, different structural formula = Structural Isomerism (:
