Question

WHAT IS THE GENERAL FORMULA FOR ALKANE? C?H?

Answer 1

WHAT IS THE NAME OF THIS SKELETAL FORMULA?

Answer 2

IUPAC rules states that you should name it according to the longest chain. The others are just groups AND in the lowest number possible.

The longest chain is 7 - hepta
and there are no double or triple bonds, so you can just use the suffix "ane"
and you have a methyl and an ethyl group in positions 2 and 4, respectively.
Now, just put it all together. And you have your name.

Answer 3

Oh, and the general formula for a saturated alkane is: \(C_nH_{2n+2}\)

Answer 4

so the condensed formula is 2-ethyl 4-methyl heptane??

Answer 5

Not quite. Very close. But there ethyl group is NOT on the 2 position.

Answer 6

oh, is it 2-methyl 4- ethyl heptane
