    Chemistry Why is an octahedral complex optically active despite having a plane of symmetry?

    Shown above is an octahedral coordination complex and it's mirror image. The complex has a plane of symmetry (shown in the left diagram, a diagonal plane passing through bottom left and top right corner, perpendicular to the square plane) ... but still it's mirror image is non-superimposable ...

    Stability of tropylium cation vs triphenyl methyl cation

    Homework Statement The textbook "Organic Chemistry by O P Tandon" says that the tropylium cation (cycloheptatri-2,4,6-enyl cation) is more stable than the triphenylmethyl cation ( Ph3C+) (phase/solvent not mentioned). Is this correct assuming it's in a non-polar medium ? On a related note, are...

    Steric inhibition of protonation in o-substituted anilines

    Homework Statement According to my textbook (Organic Chemistry by Solomon & Fryhle) "When an o-substituted aniline is protonated (at the N), increase of H-N-H bond angle leads to steric hindrance with the group at the o-position. This makes this protonated conjugate acid unstable and makes the...

    Is 4-(Bromohydroxymethenyl)-1-chlorocyclohexan-1-ol Optically Active?

    in the first image, under "optical isomerism in alkylidenes" , the middle compound in the second row is said as "optically inactive" If the structure is as shown in https://chemistry.stackexchange.com/questions/58630/why-is-1-ethylidene-4-methylcyclohexane-chiral then it should be optically...

    Distance to 3rd and 5th nearest ion to S2- in ZnS structure

    Hey folks ZnS has a ccp structure with S2- ions forming FCC lattice with Zn2+ ions at half the tetrahedral voids Attached is a table showing no. of nearest neighbours and their distance for an S2- ion 'a' is edge length of the unit cell I want to know how the distance to the 3rd & 5th...
