In order to synthesize a complex organic molecule, the
chemist should at least illustrate or imagine the bonds that are in need to be
cut down or to separate in order to obtain the compound that can be easily
changed.
I believe the answer is C: "<span>It occurs when a hydrogen atom bonds with electropositive atoms."</span>
The subscript 2 indicate that there are two atoms of chlorine in the compound.
<u><em> Explanation</em></u>
Subscript in the chemical formula indicate the number of atoms of the element immediately before the subscript.
In MgCl₂ there are two(2) atoms of chlorine since Subscript 2 is immediately after chlorine.
Explain, in terms
of both atoms and molecular structure, why there is no isomer of CH3OH.
There is no isomer of CH3OH or methanol because it
contains only one carbon atom. And also, the structure is tetrahedral, having
four substances attached to the carbon atom.
