Multiple Choice

Which of the following statements correctly describes the Lewis dot structure of hexane (C6H14)?

Hexane consists of a chain of six carbon atoms, each bonded to enough hydrogen atoms to satisfy the octet rule, with only single bonds present.

Hexane contains a ring of six carbon atoms, each bonded to two hydrogen atoms, with alternating single and double bonds.

Hexane has a chain of six carbon atoms, each bonded to one hydrogen atom, with triple bonds between the carbons.

Hexane consists of six carbon atoms bonded in a branched structure, with each carbon bonded to three hydrogen atoms.

Verified step by step guidance

Recall that hexane (C6H14) is an alkane, which means it contains only single bonds between carbon atoms and follows the general formula CnH2n+2.

Understand that in alkanes, carbon atoms form a continuous chain (not a ring or branched structure unless specified) and each carbon atom forms four single covalent bonds to satisfy the octet rule.

Recognize that each carbon in hexane is bonded to enough hydrogen atoms so that the total number of bonds around each carbon equals four, ensuring the octet rule is met.

Note that hexane does not contain double or triple bonds, nor does it form rings; it is a straight-chain alkane with single bonds only.

Therefore, the correct Lewis structure of hexane is a chain of six carbon atoms, each bonded to the appropriate number of hydrogen atoms to complete four single bonds per carbon.
