What is the iupac name for ch3-ch2-ch2-ch3?

Answer 1

You should count the carbons first by counting the longest chain possible, if there are multiple bonds, then the multiple bonds must be in the chain. Find the straight chain first if you can. Once you have the number of carbons you will know which prefix to use which is what the first person who answered showed youshowed you. Alkanescontain single bonds, alkenescontain doublebond, alkynescontain triple bondsThen if its an alkane, it ends with -ane, alkene ends with -ene, alkyne ends with -yne.

So 3 carbons, 8 hydrogens (CnH2n+2..C3H8) is the formula for propane.

Answer 2

In organic chemistry, CH3CHCH3 is called isopropyl group of atoms related to propane which attaches to another atom or group at the second carbon.

In IUPAC nomenclature isopropyl is named propan-2-yl. As an example, isopropyl acetate would be called propan-2-yl acetate.
