(a)
To determine: If the given compound shows cis-trans isomerism and its structure if applicable.
Interpretation: The compound that shows cis-trans isomerism is to be predicted and the possible structure is to be drawn.
Concept introduction: Isomers are the compounds with similar formula and different structures. Stereoisomers are a type of isomers in which arrangement of atoms differ in space. Geometric isomers are one of the types of stereoisomers. These are of two types and are named as, cis and trans isomers.

CH3 d. more than on choice is correctarrow_forwardWhich of the following statements can be used to prove that carbon is tetrahedral? a. CH3Br does not have constitutional isomers. b. CBr4 does not have a dipole moment. c. CH2Br2 does not have constitutional isomers.arrow_forwardC. 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.

- A. Structural Isomerism of Alkanes 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.
