Concept explainers
Interpretation:
From the given compounds the one having the larger energy difference between gauche and anti-conformations about the indicated bond is to be stated with explanation..
Concept introduction:
Newman projection is a way of representing the groups attached to carbon atoms in the
The energy of the conformers varies with change in their dihedral angle. The plot of this variation is known as potential energy curve.

- Draw the structure of trans-1,4-dimethyl cyclohexane. You do not have to explicitly draw H atoms.arrow_forwarddraw the skeletal (line-bond) structure of (2S, 4R)-2-bromo-4-ethylheptanearrow_forwardAs you can see from Table 11.4, each CH2 group added to the carbon chain of an alkane increases its boiling point. This increase is greater going from CH4 to C2H6 and from C2H6 to C3H8 than it is going from C8H18 to C9H20 or from C9H20 to C10H22. What do you think is the reason for this differencearrow_forward
- The empirical formula of X is C3H5CIO If X is an optically alkanal, give the structural formula of X and draw this pair of enantiomers.Structural formula of X : If X has a C=C bond and a saturated OH group (i.e. The OH group does not attach to the C=C), give the structural formula of X if X shows cis-trans isomerism. Draw the pair of cis-trans isomers.Structural formula of X :arrow_forwardDraw the skeletal (bond-line) structures of all isomers of C4H8O (including configurational isomers) that contain an alkene and an ether. There should be 5 structures.arrow_forwardDraw the formula of C6H9BrO2 with a cyclopentane ring.arrow_forward
- 12. Write bond-line structural formulas for (a.) two primary alcohols, (b.) a secondary alcohol, and (c.) a tertiary alcohol-all having the molecular formula CaH100.arrow_forwardFor the following, you must draw an appropriate structure that has the chemical formula C5H7O2Cl with the indicated functional group(s) and/or property. In each case, identify any other functional groups in the molecule you draw, that were not indicated in the question. You may use Lewis or bond- line structures to draw your molecules. You may not use the same structure to answer more than 1 question. a) An acyclic molecule that cannot form hydrogen bonds with itself b) A tertiary chloride c) A cyclic etherarrow_forwardExplain the concept of Cyclohexane Conformations ?arrow_forward
- Compounds X and Y have the formula C6H₁2. Both X and Y react with one molar equivalent of hydrogen in the presence of a palladium catalyst to form 2-methylpentane. The heat of hydrogenation of X is less than that of Y. X and Y react with HBr to form a mixture of the same bromoalkanes, and they both undergo hydroboration/oxidation to give a mixture of the same alcohols. What is the structure of Y? • In cases where there is more than one answer, just draw one. MAVI Sn [F ? ChemDoodlearrow_forwardCompounds X and Y have the formula C6H12.

Can any of these structures give rise to geometric (cis-trans) isomerism? If so, show the cis and trans stereoisomers. b. Draw and name the eight cycloalkane structures of formula C6H12 that do not show geometric isomerism. c. Draw and name the four cycloalkanes of formula C6H12 that do have cis-trans isomers. 2. Each of the following descriptions applies to more than one alkane. In each case, draw and name two structures that match the description.
