In `H_3C-CH_2-C(CH_3)_2-CH_2CH(CH_3)_2` ,identify `1^@,2^@,3^@` carbon atoms and give the number of H- atoms bonded to each one of these.

Explanation

`H- underset(underset(H)(|))overset(overset(H)(1^(@)|))(C) - underset(underset(H)(|))overset(overset(H)(2^(@)|))(C) - underset(underset(CH_(3))(1^(@)|))overset(overset(overset(1^(@))CH_(3))(|))(C) - underset(underset(CH_(3))(1^(@)|))overset(overset(overset(1^(@))CH_(3))(|))(C) - H`
Number of H-atoms attached to `1^(@)` carbon atom = 15
Number of H-atoms attached to `2^(@)` carbon atom = 4
Number of H-atoms attached to `3^(@)` carbon atom = 1
