A characteristic of a carbocation is that it will rearrange to a more stable act

Question

A characteristic of a carbocation is that it will rearrange to a more stable action if possible, it will add a nucleophile if one is available, it will eliminate a proton in the presence of a base. All of the above. None of the above. In a chemical reaction that proceeds by a radical mechanism, how would you categorize the steps that are shown below? The major type of reaction that alkanes undergo is Nucleophile Additions Electrophilic Substitutions Radical Additions Radical Substitutions None of the above. Which of the compounds shown below will undergo hemolytic bond cleavage most easily (i.e. at the lowest temperature)? CH_3 - Br CH_3CH_2 - Br (CH_2)_2 CH-Br(CH_3)_3C-Br An alkane showed a molecular ion (M^+) at m/z = 70. It gave a single product when treated with Cl_2 under irradiation (i.e. hv). Suggest a compound that fits these criteria.

Explanation / Answer

1)
carbocation rearranges to form stable carbocation
Due to + charge it attracts nucleophile to itself
It can give a H+ and can become more stable alkene (This is hyperconjugation)
Answer: d

2)
in both the steps,
the free radical is there on both reactant as well as product side. Hence they are both chain propagation step
Answer: chain propagation step
