4. The compound CH3(CH2)5CH3 is called:
A) hexane
B) pentane
C) heptane
D) octane

c.

explanation:

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

the answer is c.the valence of the atoms combine .
