WebSep 16, 2024 · The breakage and formation of bonds is similar to a relationship: you can either get married or divorced and it is more favorable to be married. Energy is always released to make bonds, which is why the enthalpy change for breaking bonds is always positive. Energy is always required to break bonds. WebAttack by the alkene nucleophile (1) causes the bromine-bromine bond to break (2) so that bromine doesn’t end up with more than 8 valence electrons. Experiments suggest that there is no discrete carbocation intermediate, so the bromine must donate a pair of electrons to the other end of the alkene as it is being attacked (3).

WebWhat is the longest wavelength of radiation that possesses the necessary energy to break the bond? Express your answer with the appropriate. The energy from radiation can be used to cause the rupture of chemical bonds. A minimum energy of 242 kJ/mol is required to break the chlorine–chlorine bond in Cl2. WebSep 12, 2024 · It follows that breaking bonds requires energy. When the bond breaking process is homolytic there is no residual ionic attraction because there are no charges on the products, so the energy required to dissociate the bond is a good measure of how strong that bond is. Table 9.1 on page 237 of Atkins & Carey lists such "Bond …

WebTrue. Radicals undergo two main types of reactions. A radical may react with a _______ bond, or add to a ______ bond. In both cases, reaction with the radical causes a bond to break. sigma, pi. Select all the statements that correctly describe the structural characteristics of radicals. - A carbon radical is trigonal planar. WebFor this specific reaction, nope! the X-X (where X is a halogen) bond would be broken the same way, everything would react similarly, though bromination would proceed more slowly (and require some heat). Fluorine would react even faster. I believe the wavelength required to break the bond is different, but I could be wrong on that.
