Draw a 3 dimensional model for a molecule

Question

1. Draw the correct Lewis dot

CH₄

H

|

H - C - H

|

H

2.Count the number of groups of electrons around the central atom. A group is a lone pair of electron, single bond, or a multiple bond. Use this number to determine the type of hybrid orbitals used in bonding and the bond angle.

Carbon - 4 single bonds = sp³

H - 1 single bond- s

109.5^o

3.draw and label lobes corresponding to the hybrid orbitals determined in in #2 above. Show overlap of orbitals in the case of sigma bonds.

4.Pi bonds can be depicted by showing overlap of the p orbitals.

Answer 1

We cannot easily draw on this Wyzant platform, so we'll do the best we can to explain how to go about answering this question.

(1). Lewis dot for CH₄

As you have drawn it with C in center and 4 H atoms around it. Where you show the 4 single bonds, simple replace them with 2 dots each

(2). There are 4 groups of electrons.

The C is sp³ hybridized

(3). Again, cannot draw this on this platform.

(4). There are no pi bonds so nothing to show. All bonds are σ (sigma) bonds made by overlap of 2 sp³ hybrid orbitals.
