The number of different HNMR signals represent the number of different hydrogens. Here are the steps you need to do to correctly identify them.

1. Label all of the hydrogens in a molecule so you don't accidentally miss one, and don'd put a signal where the hydrogen in missing. In order to label the hydrogens, we need to remember that a carbon wants to have 4 bonds. Depending on how many bonds the carbon has, is how many...

Both molarity and molality are measures of concentration, or how much solute is dissolved in solvent. Let's first get acquainted with a couple of terms.

Solute -  what gets dissolved

Solvent - what the solute dissolves in

Solution - solute and solute together 

Now, we can write out formulas for our two terms.

Molarity(M) = moles of solute/ Liters of solution

Molality(m) = moles of solute/ kg of solvent

As evident from the form...

To arrange alkenes in order of stability, we need to know that the most substituted the double bond is, the more stable the alkene is. Alkenes can be divided into four categories: monosubstituted (double bond is directly attached to one carbon), disubstituted (double bond is attached to two carbons), trisubstituted (double bond is attached to three carbons), and tetrasubstituted (double bond is attached to four carbons)...

Lewis Dot structure is a representation of how electrons are arranged in a molecule.

To correctly draw lewis dot structures we need to follow the following six steps.

1. Calculate the total number of valence electrons

2. Connect atoms in a molecule using bonds

3. Subtract electrons used in bonds from the total electrons calculated in part 1

4. Use remaining electrons to make outer atoms happy (octet, 8 electrons) but rem...

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 ex...
