question_answer 1)

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.

Answer:

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.
