What is 2-methyl-1,3- Butadiene?

Question

What is 2-methyl-1,3- Butadiene?
Please give structural formula.

Answer 1

You can break the name down:

2-methyl means that there's a methyl group (-CH3) on the second carbon.

buta- means that the core molecule is butane (C4).

1,3 diene tells you that there are double bonds (-ene) that there are two of them (di-) and their locations on the core molecule (off carbon 1 and 3).

So the molecule looks like this:

.............H............H..........
................\........./..............
.H..............C.=.C...............
....\.........../.........\..............
.....C.=. C............H..........
..../...........\..........................
.H..............CH3.................


Hope that helps!

Answer 2

The main part of the compound is a 4-carbon chain (buta). The 1,3 diene means that there is a double bond between the first and second carbons, and the third and fourth carbons. 2-methyl means that there is a CH3 group attached to the second carbon.

It all according to the IUPAC naming convention

Answer 5

Although measures and precautions are taken to prevent pollution, it is impossible to contain it all 100%. One such pollutant is what is called "coke dust" which is a very fine dust, black in color, easily noticed if you happen to drive a white car. It is a byproduct of the refining process. In addition to air pollutants, what the public does not see is stuff that is spilled all over the ground on an almost daily basis.
