Explain 1,3 and 1,5 sigmatropic rearrange ment with suprafacial and antrafacial concept |
|
Answer» A sigmatropic REACTION in organic chemistry is a pericyclic reaction wherein the net result is one σ-bond is changed to another σ-bond in an uncatalyzed intramolecular reaction.[1] The name sigmatropic is the result of a compounding of the long-established sigma designation from single carbon–carbon bonds and the Greek WORD tropos, meaning turn. In this type of rearrangement reaction, a SUBSTITUENT moves from one part of a π-bonded system to another part in an intramolecular reaction with SIMULTANEOUS rearrangement of the π system.[2] True sigmatropic reactions are usually uncatalyzed, although Lewis acid catalysis is possible. Sigmatropic reactions often have transition-metal catalysts that form INTERMEDIATES in analogous reactions. The most well-known of the sigmatropic rearrangements are the [3,3] Cope rearrangement, Claisen rearrangement, Carroll rearrangement, and the Fischer indole synthesis. |

Why transition Element show various oxidation state? |
|
Answer» These elements show VARIABLE oxidation STATE because their valence electrons in two different sets of orbitals, that is (n-1)d and ns. The energy difference between these orbitals is very less, so both the energy levels can be used for BOND formation. THUS, transition elements have variable oxidation states.Explanation: Please mark as BRAINLIEST answer. |

|
Answer» .04 N solution of a weak acid has specific conductance 4.23 × 10−4 MHO cm−1 and degree of dissociation is 0.0612. To find:The equivalent conductance (Ohm em equiv L) of weak acid at INFINITE dilution.Solution:From the given information, we have the data as follows.0.04 N solution of a weak acid has specific conductance 4.23 × 10−4 mho cm−1 and degree of dissociation is 0.0612. A = k × 1000/NA = 4.23 × 10^-4 × 1000/0.04A = 10.575α = A/A∞⇒ A∞ = A/αA∞ = 10.575/0.0612∴ A∞ = 172.79Therefore, the equivalent conductivity at infinite dilution is 172.79 |
