Structural Representation of Organic Compounds

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.

State the hybridisation of carbon in ethene.

$\left(\mathrm{A}\right) \mathrm{sp}; \left(\mathrm{B}\right) {\mathrm{sp}}^2; \left(\mathrm{C}\right) {\mathrm{sp}}^3$.

Enter your correct answer as A, B or C.

Define framework model of ${\mathrm{CH}}_4$ ?

Define space filling model of ${\mathrm{CH}}_4$ .

Wedge-and-dash representation is used to show non-planar bonds in the ${\mathrm{CH}}_4$ molecule.

${\mathrm{CH}}_4 \mathrm{is} {\mathrm{sp}}^3$ hybridised molecule with tetrahedral geometry of bonds( Wedge-and-dash representation of ${\mathrm{CH}}_4$).
