Draw the structure of an alkane or cycloalkane that has more than three but fewer than ten carbon atoms, and only primary hydrogens. (there are several possible structures. it is enough to draw any one of them, but you may draw two or more if you want to.)

The structures are shown in the figure.

Explanation:

The primary hydrogens are those which are attached to primary carbon.

Primary carbons are the carbons which are attached to only one carbon.

Primary carbons is bonded to three hydrogens.

In order to draw such structure we will draw structures which will have carbon with three hydrogens or no hydrogens (quaternary)

The structures are shown in the figure with clear marking.

im not exactly sure but i think its b!
