Using the data provided, calculate the multiple bond energy(kJmol−1)of aC≡Cbond inC2H2. That energy is(take the bond energy of aX−Hbond as350kJmol−1). 2C(s)+H2(g)→C2H2(g),Δ=225kJmol−1 2C(g)→2Cg),ΔH=1410kJmol−1 ...
To solve the question regarding the assertion and reason provided, we will analyze each part step by step.Step 1: Analyze the Assertion (A) The assertion states that the bond energy of the Cl-Cl bond is more than that of the F-
The value of the Pt+ Cbond energyis also interesting. Clearly, this bond energy does not fit the correlation with the C C bond energy. This is simply explained by noting that Pt+has occupied 5dπ orbitals that can donate into the empty 2pπ orbital on C. Thus, PtC+has a covalent doub...
The molecular structures and energies of hydrocarbons containing very short nominally single C–C bonds were calculated by high-level ab initio calculations. The 'squeeze energies' (SqEs) pertaining to the shortening of central C–C bonds are found to correlate very well with central short C–C...

THE value of the energy of the central C-C bond in diphenyl (that is, the heat of dissociation of the molecule into two radicals (or atoms) formed by the fission of this bond) is of considerable interest. The difference between the energy of this bond and the energy involved in the C...

atoms. The simplest interpretation of the decrease in energy that occurs when electrons are shared is that both electrons lie between two attracting centres (the nuclei of the two atoms linked by the bond) and hence lie lower in energy than when they experience the attraction of a single ...
