Choose the answer that ranks the following species in order of increasing carbon-carbon bond strength (strongest bond last): C 2 H 4 C 2 H 2 C 2 H 6 Weakest Strongest A. C 2 H 4 < C 2 H 6 < C 2 H 2 B. C 2 H 6 < C 2 H 4 < C 2 H 2 C. C 2 H 2 < C 2 H 6 < C 2 H 4 D. C 2 H 2 < C 2 H 4 < C 2 H 6 E. C 2 H 6 < C 2 H 2 < C 2 H 4 Solution: We must begin by drawing the correct lewis dot structures. Next, we need to know that a triple bond is stronger than a double bond which

What is the Lewis Dot Structure of N 2 H 4 Solution: Steps for Drawing Lewis Dot Structure: Calculate the total number of valence electrons in a molecule (group number = number of valence electrons) Draw out your molecule and put lines between atoms (bonds) Subtract electrons used in bonds (2 electrons per bond) from the total number of valence electrons Use the remaining electrons to make outer atoms happy (octet). Keep in mind hydrogen only wants 2 electrons. If there are a
