and what about this? |dw:1441473582642:dw|
I'm not sure but do you think it is Propylbenzene?
for the 1st one
I looked it up on the internet but I'm not sure the formula for propylbenzene is C9H12….
it is not a benzene, it lacks the internal double bonds. the cyclic structure is a cycloexane for sure :)
you use "cyclohexyl" as a name for the side chain since the double bond takes precedence over the ring.
do you still need help ?
try to identify the parent chain first there are rules
On chemspider i found something similar. Maybe i can call it like: (1-propene) cyclohexane
