Types of atomic bonding. Describe both which type(s) of bonding are present in the following materials and how that type of bonding affects the properties of that material. Consider the electronegativity differences between elements where applicable to justify your comments. (a) H2O in its liquid form. Why does water expand when it freezes

i'm not sure

explanation:

i'll try whatever you got

c, liquids evaporate, creating a gas

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.
