Draw the structure(s) of the organic product(s) predicted when this compound reacts with NaBH4, ethanol then H3O . Use the wedge and dash tools to indicate stereochemistry as appropriate.

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.
