Explain with proper description with examples: difference between regioselectivity and stereoselectivity
Step by step
Solved in 2 steps
- Explain with examples: difference between regioselectivity and stereoselectivityDiscuss the meaning of the term chirality in organic chemistry? Include in your discussion the different ways in which chirality is identified and how to determine chirality by designating priority groups.Draw the skeletal (line-bond) structure of [CH₃CH₂CHC(O)CH₂CH₂CH₃]⁻. Include all lone pairs and charges as appropriate. What do the brackets and the - exponent mean for this formula?
- 5. For the molecules below assign the stereochemical configuration of the selected tetrahedral carbon chiral centers (R, S or N (not a chiral center)) and the alkene (E, Z or N (not a stereocenter)) that are indicated by the arrows (note that you do not have to assign the configuration of every chiral center in the molecule). If the atom in question is not a chiral center or is not a stereocenter circle N for neither. b) RSN RSN HO" RSN EZ N RSN НО. H₂N HO HO OH HO OH RSN RSN CH3 НИ H3 CH₂ RSN RSN RSN EZ N RSNStereoisomers share the same connectivity and differ only in the way their atoms are arranged in space. Draw the structure of a compound that is a stereoisomer of cis-1,2-dimethylcyclobutane.(Note that the question asks for a different stereoisomer of the named compound and not the named compound itself.)Use the wedge/hash bond tools to indicate stereochemistry where it exists.In cases where there is more than one answer, just draw one.write structural formulas for all the compounds that are trichloro derivatives of cyclopropane, which are chiral and which are achiral?
- Does stereochemistry of a molecule matter? Give a real-life example where knowing the stereochemistry of a molecule is important.2. (a) Define and give one example of a geometry that is coordinatively unsaturated. (b) Define and give one example of a geometry that can be stereochemically non-rigid.Draw tartaric acid - 2,3-Dihydroxybutanedioic acid (-dioic means two carboxylgroups), how many stereo isomers will this molecule have? How many of these isomers will be chiral?
- Chiral compounds have a so-called asymmetric carbon atom in the molecular structure, and are opticalactive. Study the following organic molecule containing two −? − ? – groups (thiol) andwhich is a medicine against various types of metal poisoning, including against arsenic, mercury and lead: Image Based on this skeletal structure, judge whether this molecule is chiral. Give reasons for your answer.Suggest an IUPAC name for the molecule that takes into account all the given functional groups.Draw a dash and wedge representation of all the possible stereoisomers of 1,2- dichlorocyclopentane. Describe their relationship to one another and then describe their optical activity:parce Nitroethylene, 1,C-CHNO, is a sensitive compound that must be prepared with great care. Attempted purification of nitroethyfene by distillation often results in low ecovery of product and a white coating on the inner walls of the distillation apparatus. Draw a structure for the white coating. • You do not have to consider stereochemestry • You do not have to explcitly draw H atoms. • Do not incude lone pairs in your answer. They will not be considered in the grading • In cases where there is more than one answer, just draw one. • Use RI groups to indicate the points where the polymer repeats.
