What is the correct formula of neopentane?

Draw the complete formula of methane according to the structural model.

In Wedge-Dash notation for three-Dimensional representation of an organic molecule, the dashed bond represents.

_____ model only the bonds connecting the atoms of a molecule and not the atoms themselves are shown in the molecule of methane.

In the ball-and-stick model, both the atoms and the _____ are shown in the molecule of methane.

The space-filling model of methane emphasises the relative size of each atom based on its van der Waals radius.

A compound $\text{'}A\text{'}$ contains $C$ and $H$ only, and has molecular mass $72.$ Its photochlorination gives a mixture containing only one monochloro and two dichloro hydrocarbons. Deduce the structure of $\text{'}A\text{'}.$
