Concept explainers
Interpretation:
The bond angle around a carbon atom and the geometry of a carbon atom when it forms two single bonds and one double bond has to be described.
Concept introduction:
Bond angle is the angle between two bonded pairs or two bonds in a molecule. The molecular geometry represents a three-dimensional arrangement of atoms present in the molecule. Atomic orbitals mixed to form a new hybrid orbital of equal energy. The geometry and bond angle of carbon compounds is determined from the hybridization of the carbon atom. The table to identify the bond angle and geometry of the molecule from hybridization is as follows:

Introductory Chemistry: An Active Learning Approach
- How many electron pairs are shared when a triple bond exists between two carbon atoms? What must he the geometric arrangement around the carbon atoms in a triple bond? Draw the Lewis structure of a simple molecule that contains a triple bond.arrow_forwardWhat is the difference between the hybridization of carbon atoms' valence orbitals in saturated and unsaturated hydrocarbons?arrow_forwardWhat is the difference in bonding and in the general molecular formula between an alkene and an alkane with the same number of carbon atoms?arrow_forward
- 4: Draw out the abbreviated structural formula of the following molecules. 4-Methyl-2-hexene 2-Methyl-2-hexene 2-Hexene 5: Draw the structure of 2-Butene, labeling the n bond and all the B bonds. 6: Draw all the structures possible with the formula CSH8.arrow_forwardTake cis-2-butene What is the bond angle and molecular geometry around each of the 2 middle carbon atoms? Rotation around double bonds is not possible. Describe how this affects the molecule. How does this compound compare with butane?arrow_forwardFor every one double bond in a structure of a hydrocarbon, there is one less hydrogen than found in an alkane with same number of carbons.arrow_forward
- Sketch the hydrogen bond(s) that form between ethanol and nitrogen trihydride and dihydrogen monoxide. Show the proper VSEPR shapes of all molecules (meaning VSEPR shapes with proper bond angles) and use dotted or dashed lines to indicate the hydrogen bonds. Indicate 4 different H-bonds between: 1) ethanol and nitrogen trihydride 2) ethanol and dihydrogen monoxide 3) dihydrogen monoxide and nitrogen trihydride and then 4) between the two ethanol molecules.arrow_forward2.
