Writing Chemical Formulas

Postby Chem_Mod » Tue Aug 30, 2011 12:25 am

When we're asked to draw the structure of a compound, why does it change the way propyl is written? The book writes it out as CH2 CH2 CH3 instead of CH2CH2CH3. Does it make a difference if they're written separately or distributed instead like CH3CHCH3, and if so when do we do it like that ?

Both CH2 CH2 CH3 and CH2CH2CH3 will be accepted as correct answers. But it DOES make a difference between CH2CH2CH3 vs. CH3CHCH3 because it's propyl vs. isopropyl. Therefore, be careful when naming it as well.
