Question

2. Explain why cycloheptatriene, shown below, will react with an acid to form a carbocation (the tropyllum ion)? 3. Predict the major organic product in the following reaction HBT 4. What is the major product of the following reaction? OH HINO, TO CHÚCH . 5. What is the major product of the following reaction? ME E1,0 2)H,09 6. We learned that the bond dissociation ener() of the highlighted C-H bond in toluene is lower than the DE of the C-H bond in isobutane. Explain why it is easier to homolytically break the C-H bond in toluene than in isobutane. CH, HCC BDE 404 /mol BDE - 372 N/mol 7. In general, which one of the functional groups below does not react with Gripsard reagents in nucleophilic addition reactions? a) esters b) ketones epoxides d) carboxylic acids Il Consider the conversion of 1-butanol to each of the compounds shown below, in which conversion is an adding needed?

Answer 1

2) Because tropylium cation is aromatic in nature . And aromatic compounds are srable .

6) lesser energy is required in Toluene to break the bond , because benzylic radical formed is more steble than the tertiary radical which formed from isobutane.

7) D option is correct. Carboxylic acids do not react with grignard reagent .

8) In the aldehyde formation , oxidising agent is needed.
