How to recognize intermolecular forces?
Intermolecular forces are forces of attraction between molecules. These forces influence properties of substances such as boiling and melting points, phases at room temperature, viscosity and many more. Intermolecular forces can be divided into 4 major categories: 1. ION-ION This is the strongest intermolecular force. It is present in all ionic compounds. To recognize it, look at the formula and see if it has metal with a nonmetal, or metal with polyatomic ion. 2. HYDROGEN BO

How to best prepare for chemistry finals?
It's almost december and that means it's finals time! This can be very overwhelming and stressful. At Transformation Tutoring, we came up with tips on how to best prepare for your chemistry finals. 1. Make a to-do list. List items in terms of priority. Since time is limited, it is important to focus on the most important tasks that need to be done. Make a big plan for the two upcoming weeks with major milestones (for example, review chapter 3 by Monday). Also make a todo lis

Which of the following substrates would react most efficiently in a substitution reaction with NaCN?
Which of the following substrates would react most efficiently in a substitution reaction with sodium cyanide (NaCN)? (A) 1-iodohexane
(B) 1-fluorohexane
(C) (R)-2-bromohexane
(D) chlorocyclohexane
(E) 1-bromo-1-methylcyclohexane Answer: (A) 1-iodohexaneA Solution: We first must figure out which reaction does the question ask about. The question mentions substitution reaction, thus either SN1 or SN2. We are also given NaCN as the nucleophile. We need to remember that SN1
