antiperiplanar meaning in Hindi

Examples

1. This reaction proceeds most readily when the nucleophile attacks the species that is antiperiplanar to the leaving group.
2. Thus, it is the bulkier group that ends up antiperiplanar to the peroxide group making it the group that migrates.
3. However, transition state bending allows the in-plane ? bonds to have a more antiperiplanar arrangement that facilitates interaction.
4. As mentioned, the substituent that is antiperiplanar to the peroxide group in the transition state will be the group that migrates.
5. The case of higher alkanes is more complex but based on similar principles, with the antiperiplanar conformation always being the most favored around each carbon carbon bond.
6. Relief of steric strain dictates that the alkyl residue R of the enamine and the imine group are antiperiplanar on approach which locks in the syn mode of addition.
7. If the bulkier group is placed antiperiplanar to the peroxide group, the gauche interaction between the substituent on the forming ester and the carbonyl group of the peroxyacid will be reduced.
8. As known from the orbital orbital interaction requirement, if this stereoelectronic effect is to be favored, the donor acceptor orbitals must have a low energy gap and they must retain antiperiplanar geometry to allow for perfect interacting direction.
9. For instance in certain vicinal hydrogen atoms in an antiperiplanar configuration both in a crystal lattice ( X-ray diffraction ) and in solution proton ( NMR coupling constants ) normally reserved for the most bulky groups i . d . both arenes:
10. The two types of terms can be combined so as to define four ranges of angle; 0?to ?0?synperiplanar ( sp ); 30?to 90?and  " 30?to  " 90?synclinal ( sc ); 90?to 150?and  " 90?to  " 150?anticlinal ( ac ); ?50?to 180?antiperiplanar ( ap ).
