You only change the position of the Cl, not the number. This process happens in stages.

The MS says dichlorobutane or 2-chlorobutane (i chose this one as my final answer)..
So how is dichlorobutane written ?
nid404:
2-chlorobutane is possible....dichlorobutane happens in the second step
What you have drawn is dichlorobutane
2-chlorobutane is Cl on the 2nd carbon

When drawing a magnification of something in Bio, Does everything have to be in the right proportion? Meaning if you've magnified the legs of an insect by 2, then the body and head and eyes should also have to be magnified by 2. Does everything have to be exact?
How does magnification work???
nid404:
yes everything is magnified by the same amount...so all the parts should approximately be magnified equally
magnification= observed size/ actual size

I suck at drawing so what's the easiest way to do this??? I'm doing May-June 2003 Paper 6 Question 3.
