SUMMARY

The correct name for the molecule in question is propene, specifically 1-propene, which consists of a three-carbon chain with a double bond. The term "2-Methyl-1-Propene" is incorrect as it suggests a four-carbon structure, which is actually isobutylene. The methyl prefix is unnecessary in this context, as propene is the widely accepted nomenclature for this compound, also known as propylene.

I've attached the image. Is the naming of this molecule correct? If so, why is the methyl prefix necessary? The three carbon chain + the double bond makes it 1-propene...

If not, would the correct name be methylethene?

propene is the correct name the 1 is not necessary, more commonly it is known as propylene
 
Thanks. So methylethene=propene?
 
Not quite, it is just propene 3 carbons one double bond. I am not sure where the methyl propene came from. 2-Methyl propene would have four carbons it is also known as isobutylene, here is a link
