- Which objects are asymmetric (have no plane of symmetry): (a) a circular clock face; (b) a football; (c) a dime; (d) a brick; (e) a hammer; (f) a spring?arrow_forwardTo the following statement, answer true or false and explain your answer. Q)To be optically active, a molecule must have a chiral center.arrow_forward(S)-2-Bromobutane has a specific rotation of +23.1°. Suppose that a solution is made by dissolving 20.00 g of (S)-2-bromobutane in 1.00 L total solution. What would be the measured rotation of plane-polarized light sent througha 10.00-cm tube containing that solution?arrow_forward
- What type of stereochemistry, S or R, does the chiral center in this molecule have?arrow_forward< Question 22 of 67 A solution of a chiral compound was prepared by dissolving 15.67 g in 16.00 mL of solvent. The solution was placed in a tube that is 1.00 dm long. What is the specific rotation of light if the observed rotation was determined experimentally to be +62.41°? 1 4 7 +/- 2 сл 8 . 6 S O Submit C x 100arrow_forwardPolymers such as polypropylene contain a large number of chirality centers. Would you therefore expect samples of isotactic, syndiotactic, or atactic polypropylene to rotate plane-polarized light? Explain.arrow_forward
- Write the name of the following compounds. Which of them are stereoisomers? Which of them are optically active? Use cis-trans, (E)(Z) nomenclature and assign the absolute configuration (R),(S), if any to each chiral center.arrow_forwardIs this a chiral compound? Illustrate why.arrow_forwardA well known non steroidal anti inflammation drug NSAID exists in two sterochemical forms. Only one is biologically active. Below is the structure of the biological active form. Identify the chiral center and determine if it is the R- or S- stereoisomer.arrow_forward
- How many chiral centers exist in the following molecule structure A?arrow_forwardThe quantitative differences in biological activity between the two enantiomers of a compound are sometimes quite large. For example, the D isomer of the drug isoproterenol, used to treat mild asthma, is 50 to 80times more effective as a bronchodilator than the L isomer. Identify the chiral center in isoproterenol. Why do the two enantiomers have such radically different bioactivity?arrow_forwardWhich of these structures is chiral?arrow_forward
