The order of decreasing ease of abstraction of hydrogen atoms in the following molecule 
- A \(\mathrm{H}_{a}>\mathrm{H}_{b}>\mathrm{H}_{c}\)
- B \(\mathrm{H}_{a}>\mathrm{H}_{c}>\mathrm{H}_{\mathrm{b}}\)
- C \(\mathrm{H}_{b}>\mathrm{H}_{a}>\mathrm{H}_{c}\)
- D \(\mathrm{H}_{\mathrm{c}}>\mathrm{H}_{\mathrm{b}}>\mathrm{H}_{a}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{H}_{a}>\mathrm{H}_{c}>\mathrm{H}_{\mathrm{b}}\)
Step-by-step Solution
Detailed explanation
Abstraction of \(\left(\mathrm{H}_{a}\right)\) hydrogen atom results in the formation of \(3^{\circ}\) allylic carbocation wheres abstraction of \(\mathrm{H}_{c}\) gives \(2^{\circ}\) allylic carbocation (which is less stable as compared to former one). However, abstraction of…
