The scientific method is an order of steps that is followed and the first step of scientific inquiry is often Group of answer choices

Design the experiment

Interpret data

develop a hypothesis

Developing the problem

Developing the problem

Explanation:

In order to have an experiment or to make the experiment's data useful, you must first find a problem to solve.

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.
