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.

Data Scientist
Explanation:
Data Scientist (different from a statistician) is a type of researcher that uses computer softwares to analyse and make sense of raw digital data.
Data Scientists usually combine knowledge of computer science, statistics and mathematics while using various softwares to extract information and meaningful, key insights (whether structured or unstructured) from data.
There are two popular types of data scientists: Operational Data Scientists (experts in software implementations and day to day running of the data science wing of a firm) and Exploratory Data Scientists (The real digital data miners, the researchers).
With the way the world is set up now that data is everything, data scientists are a must for every firm as the raw data every firm collects is processed by data scientists.
