The chains in normal alkanes are not really straight but zigzag because the bond angles around the carbon atoms are what

You are teaching a class in organic chemistry to grade 12 students. Outline the differences in 3 physical properties between alkanes, alcohols, and carboxylic acids. Note: they all have the same hydrocarbon length.

What type of hybridization of the carbon atoms in the organic compounds? Give an example

A. Structural Isomerism of Alkanes, continued. Construct models for the five alkanes that have the molecular formula C6H₁4. All five of your models should have the same number of each type of atom, but they should have the atoms connected in a different order. Thus the molecules they represent are structural isomers of one another. Note the tetrahedral geometry of each carbon atom. Draw an extended and a condensed structure (NOT skeletal/line angle) of each structural isomer, then determine its IUPAC name. Recall that since the IUPAC name specifies the number of each type of atom and how they are connected, each structural isomer will have a different name. Each name should very specifically describe the structure. Isomer 3: Extended Structure Isomer 3: Condensed Structure IUPAC Name: IUPAC Name: Isomer 4: Extended Structure Isomer 4: Condensed Structure

Which is most stable, cis-1,4-dimethylhexane, or the trans isomoer? Draw the structure of the more stable isomer (your structure should clearly distinguish between all axial and equatorial positions.)

Is cis,trans isomerism possible in alkanes?

Why do alkanes, alkenes, and alkynes have a relatively low boiling point? O They have no large intermolecular forces holding them together. O They have no diple moments or polarity. O They have a lot of electron density in a very small amout of space.

The average bond enthalpy for C-His 413 kJ/mol. 413 kJ of energy is required to break a mole of CH into atoms: CH(g)→C(g) + H(g), AH=413 kJ Using this information, and your answer from Part A, calculate the enthalpy change of the reaction from Part B. That is, calculate the energy required to break only the carbon-carbon bonds in benzene. Express your answer to four significant figures and include the appropriate units. > View Available Hint(s) HA AHrxn = Value Units Submit Part D Complete previous part(s) Next > Provide Feedback 9:33 PM B.

C. Alkenes 1. Construct a model of ethene (C₂H4) by joining two carbon atoms with a double bond. Toggle between skeletal and full Lewis structures by clicking the C-H tool. Note the trigonal planar geometry of the bonds around each carbon atom, and that the carbon-carbon double bond has restricted rotation. Observe that the six atoms in ethene all lie in the same plane, and the double bond is a fixed geometry within the molecule. 2. Add a CH3- group to each of the doubly-bonded carbons to create a four-carbon alkene with the double bond between carbons 2 and 3. Note that the CH3- groups can be attached in two different ways: Both CH3- groups on the same side of the fixed geometry of the double bond. The two CH3- groups on opposite sides of the double bond. Click the broom to tidy up the structures; convert each to a ball-and-stick model clicking the 2D to 3D tool. Take scr prints of your MolView structures, showing both the Lewis structure and 3D model. ● Below, draw structures for…

In terms of organic chemistry how do you know if an atom has ionic bonds or covalent bonds and how do you know if it has just one of these or if it has both? Could you provide some examples of what an ionic bond looks like, covalent bond looks like, and what an atom would look like with both of these?
