- Calculate the number of degrees of unsaturation for each molecular formula.a. C6H6b. C40H56c. C10H16O2d. C8H9Bre. C8H9CIOf. C7H11Ng. C4H8BrNh. C10H18CINOarrow_forwardName the following molecule by following IUPAC rules. Use appropriate stereochemical designations (R, S, E, or Z) as needed. Do not put spaces between dashes or commas in the answer.arrow_forwardThe heat of combustion of either but-1-yne or but-2-yne is -2577 kJ/mol (-615.9 kcal/mol), whereas the other's is -2597 kJ/mol (-620.7 kcal/mol). Match each compound to its heat of combustion. But-1-yne But-2-ynearrow_forward
- The facts in Section 5.4A can be used to locate stereogenic centers in any molecule, no matter how complicated. Always look for carbons surrounded by four different groups. With this in mind, locate the four stereogenic centers in aliskiren, a drug introduced in 2007 for the treatment of hypertension.arrow_forwardStereoisomers 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 trans-1,4-dibromocyclohexane cis-1,2-dimethylcyclobutane cis-1,3-dimethylcyclobutanearrow_forwardWhich of the following structures represent the same stereoisomer? A. only 1 and 2 B. only 1 and 3 C. only 2 and 3 D. 1, 2 and 3 Please explain.arrow_forward
- please drW this molecule confused about the Z confgurationarrow_forwardDraw all three staggered conformations for the following compound, viewed along the C₂-C3 bond. Determine which conformation is the most stable, taking into account gauche interactions and hydrogen-bonding interactions. (J. Phys. Chem. A 2001, 105, 6991-6997) Provide a reason for your choice by identifying all of the interactions that led to your decision. H₂C OH C₂ HO CH3 Which of the following is the most stable staggered conformer? Me Me *** Conformer B Me- Me Conformer A Me Conformer C Me Conformer B because the anti OH groups avoid hydrogen bonding, which is a destabilizing effect. Conformer A because there are only two gauche interactions, and hydrogen bonding between the two OH groups is a stabilizing effect. Conformer C because there is no steric strain for Me-OH gauche interactions and hydrogen bonding between the two OH groups is a stabilizing effect. Conformer B because the large OH groups are anti to each other.arrow_forwardQ1:- Which of the isomeric alcohols having formula CSH120 are chiral ? Which are achiral? Draw the enantiomers. Q2:- Which of the following compounds are chiral? Draw the stereo structures. a- 1-Chloro-2-bromobutane b- 1,2-Dichloro-3-methyibutanearrow_forward
- Fill in the boxes with the correct organic structure. You must show relative stereochemistry where necessary. You only need to draw one enantiomer if the product is a racemic mixture. 1. OsO4 2. NaHSO3 MCPBA HglO6 1. NaOH 2. HCIarrow_forwardHow are compounds I and II related? "Compound I" "Compound II" O They are different conformations of the same compound. O They are constitutional isomers. O They are cis-trans isomers. O They are completely different compounds with different formulas. ○ They are a pair of diastereoisomers. O They are a pair of enantiomers.arrow_forwardUse the following partial structure to answer the questions belowarrow_forward
