Click on the element in the periodic table to
explore the atomic radii of elements from period 3
and group 17. fill in the missing values in the
table so you can compare the atomic radii of the
elements. after the table is filled in, compare the
values in each column.

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.

i belive it is water

the answer is symmetrical : )
