You need to be able to visulaise the molecule or get yourself a set of models. Identify the chirality centres (most commonly an sp3 C with 4 different groups attached) Assign the priority to each group (high = 1, low = 4) based on atomic number (or mass if same atomic number) ...

A ketone is R2C=O; therefore, if we make R1 a CH3 group (the simplest) and the second R group a CH3 group, that makes 3 C atoms. If you take one of the R groups and try to make it smaller (like making it a H atom), one ends up with RCHO and that is an aldehyde, not a ketone.

3.15 mol / 0.250 kg = 12.6 mol/kg or 12.6 molal The boiling point of a solution is Tb = Tb(H2O) + deltaT = 100 + deltaT deltaT = Kb*m = (0.512deg.kg/mol)(12.6mol/kg) NOTE: C2H6O2 is not ethylene. It may be CH3-O-O-CH3 whose solubility could not be 12.6molal. It is a bad ...

CH4 is not. CF4 is not CH3F is. All three molecules are tetrahedral shapes. The C-H bonds are slightly polar BUT the tetrahedral shape is symmetrical and the individual bond polarities cancel so the overall polarity is zero for the molecule. Same argument for CF4. However, for...

sturctural formula
how would i the sturctural formula look for this one: dimethyl-propane: my guess that it would be like so: CH3 l CH2 l C-CH2-CH3 l CH2 l CH3 Is this right? Please visit the following: http://images.google.com/images?hl=en&safe=off&as_qdr=all&sa=N&resnum=0&q=%20%...

The Na to CN bond is ionic. The C to N bond (it's C triple bond N) is covalent, specifically sp hybridization. Certainly the molecule is polar because of the ionic nature of the molecule.

This is a bit weird to me. We're doing R and S configurations and I think of it as a steering wheel - steering to the right is an R configuration and steering to the left is an S configuration. These questions are drawn out as molecules in our book and I listed them going ...
