Compuestos del boro con hidrogeno se llaman boranos. Uno de estos boranos tiene formula empirica de h3 y un peso molecular de 28 gramos mol. Cual es la formula molecular?

you gotta add the following molecules so we can give u an answer

explanation:

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.
