• # question_answer 28) In the alkane $C{{H}_{3}}-C{{H}_{2}}-C{{(C{{H}_{3}})}_{2}}-C{{H}_{2}}-CH{{(C{{H}_{3}})}_{2}},$ identify $1{}^\circ ,\text{ }2{}^\circ ,\text{ }3{}^\circ$ carbon atoms and give the H-atoms bonded to each one of these.

In this structure of alkane, 15 H are attached to five $1{}^\circ$carbon 4 H are attached to two $2{}^\circ$carbon 1 H is attached to one $3{}^\circ$carbon.
