What occurs when potassium reacts with bromine to form potassium bromide? 1) Electrons are shared and the bonding is ionic.

2) Electrons are shared and the bonding is covalent.

3) Electrons are transferred and the bonding is ionic

4) Electrons are transferred and the bonding is covalent.

can you list the answers so i can answer

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.
