3-methyl pentane?


Yes — the longest carbon chain in that molecule is 5 carbons long, so it's some pentane variant.

But 3 methyl pentane looks like this::confused: :confused: :confused:

How come the longest chain is 5 carbon long? I see only four.
It's the same :wink: look at the LONGEST carbon chain in your original molecule.
The carbon that's furthest on the left is your methyl group and the other five form the pentane backbone. xx

Look at it again. If you think about it, you can count 5 carbons in a row before you must consider branches.

OP instead of putting the c's underneath eachother why not put one on top and one on bottom; I'm sure that will be an isomer then!

There's a chain of five carbons in the molecule, going from the bottom to the top right.

Ignore the C at the top left and you can count 5 in a row, right?

if you imagine the molecule like that and 'twist it' a bit. xx

The longest carbon chain formed is 5 carbons long. Go across 3 from the right and down 2, that's 5 carbons. The one on the left is the methyl group, and it's attached to the third carbon so it's 3-methylpentane.
yeah 3-methypentane is the name of that molecule. You always take the longest carbon chain as the main carbon chain.
