Hey....your line formula is really weird.....I think you might have added too many carbons on the left end...by fixing it a bit on that side the name would be: 5-(3,3-dimethylbutan-2-yl)-4-isopropyl-2,8-dimethyl-6-propylnonane
Organic chem is great:) as long as you don't see it as a burden you'll breeze through it!
