While I was going through some organic chemistry exercises, I came across these questions which asks me to draw the structure formulas for couple of organic compounds. But the problems is when I checked the answers, some of the formula would appear like this : HC=C-CH3 how come the H is infront of the C in this case. But another formula was CH=CCH-CH3, the C is now infront of the H rather than behind it.
What's causes this difference?
