When two nonmetals are the same like F2 the bond is lonic
Nonpolar Covalent
Polar Covalent

h let me think

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

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.
