Here’s another question for you.

6. Apply what you know about chemical bond formation between atoms and explain why the molecule with 2 carbon atoms and 6 hydrogen atoms called ethane has the arrangement

                         H     H                    and not                 H     H

                            l       l                                                   l       l

                    H - C - C - H                                        C - H - H - C

                          l      l                                                   l       l

                        H   H                                              H     H                           

Explanation / Answer

the molecule ethane would always have the first arrangement and not the second one because as we all know that carbon has four electrons in its outermost shell and hence it needs four more electrons to become stable.. in the second arrangement, one carbon has only 3 valencies fulfilled while the other one has only one fulfilled, therefore it is not a stable arrangement and would not be preferred.
