Question

What is the condensed structural formula for $2,2$ - dimethylbutane?

Answer 1

Hint: We have to see that, the structural equation of a synthetic compound is a realistic portrayal of the sub-atomic design (dictated by primary science strategies), showing how the particles are conceivably orchestrated in the genuine three-dimensional space. The compound holding inside the particle is either expressly or verifiably.

Complete answer:
In early natural science distributions, where utilization of illustrations was firmly restricted, a typographic framework emerged to portray natural constructions in a line of text. Albeit this framework will in general be hazardous in application to cyclic mixtures, it's anything but a helpful method to address basic constructions.
Enclosures are utilized to demonstrate numerous indistinguishable gatherings, showing connection to the closest non-hydrogen iota on the left when showing up inside a recipe, or to the molecule on the right when showing up toward the beginning of an equation. In all cases, all molecules are shown, including hydrogen particles.
In the consolidated primary equation, each carbon molecule is addressed exclusively, and the accompanying carbon iotas are set to the particles that are clung to that specific carbon iota. Very much like in a substance response wherein the primary carbon iota has three hydrogen particles fortified, the second carbon molecule has two hydrogen iotas; third carbon iota has three hydrogen iotas, and fourth carbon particle has three hydrogen iotas. Another more consolidated method of composing the underlying recipe is when there are two $C{H_2}$ bunches in the atom by having ${\left( {C{H_2}} \right)_2}$ in the primary equation.
Therefore,
The condensed structural formula for $2,2$ - dimethyl butane are drawn below,
$C{H_3}C{\left( {C{H_3}} \right)_2}C{H_2}C{H_3}$ .

Note:
 An underlying equation is a worked on model that can't address certain parts of compound constructions. For instance, formalized holding may not be material to dynamic frameworks like delocalized bonds. Aromaticity is such a case and depends on how to address the holding.
