Question

Is there such a thing as `"1,4-butadiene"`?

Answer 1

see below

Explanation:

I think you mean the same thing by `1,4-`Butadiene and `1,3-`Butadiene.

According to the rules of IUPAC, this molecule is to be named as `1,3-`Butadiene and not as `1,4-`Butadiene.

Answer 2

I think you are quite correct. There ain't no such thing as `"1,4-butadiene"`.

Explanation:

As you know, `"1,3-butadiene"` is `H_2stackrel(1)C=stackrel(2)CH-stackrel(3)CH=stackrel(4)CH_2`. You only have 4 carbons; so you have found a typo.....

Answer 3

No, that's a typing error. It should be comparing 1,3 butadiene with 1,2 butadiene.
