"The atoms of the elements tend to react in such a way that they acquire an electronic configuration of a noble gas." Corresponds to:
- Law of multiple proportions
- The Schrödinger Wave Equation
- Lewis Electronic Octet Theory
- Einstein's Theory of Relativity
- Bohr's Theory of Energy Levels

i don,t know so just answer mine

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.
