In isopentane and neopentane,what does iso and neo means?

Answer 1

Iso means the same. Therefore iso pentane will have 5 carbons,12 hydrogens but will have a slightly different structure, such as a branched chain instead of straight. Neo means new, it is similar to iso in this use, a slightly different form of pentane, having 5 carbons and 12 hydrogens, different from the first in structure,only

Answer 3

They are somewhat obsolete names for the substances

2-methylbutane and 2,2,-dimethylpropane

"Iso" means that the alkane is a straight chain except for a "fork" of two methyl groups at the end; so isoalkanes look like this:

CH3(CH2)nC(CH3)2H

"Neo" means that the alkane is a straight chain except for a "cross" of three methyl groups at the end; so neoalkanes look like this:

CH3(CH2)nC(CH3)3

They are not named after the longest chain, but after the overall number of carbons in the chain.

Answer 4

Isopentane is also named 2-methylbutane, so it contains a carbon bonded to three other carbons.

Neopentane is also called 2,2-dimethylpropane, so it contains a carbon bonded to four other carbons.

Answer 5

These are shortcut names for two different configurations of the hydro-carbon pentane (5 carbons).

this does not print correctly the c below should be attached to the 2nd c in the chain

this is isopentane
c-c-c-c

c

all of the carbons should be attached to the central carbon (tertiary)
c

c-c-c this is neopentane.

c

Answer 6

look at the structure and you'll see it. one has a fork the other looks more like a trident
