Assessment (Post Test)
1. Multiple Cholce! Read the statemente carefully checae the latter of your area
and write it on the space provided before the number
1. It is the tendency of an alom to atladi electron
e Polenty
Bonding b. fonte Bonding
Electronegativity
2. What accounts for the polarity of compounder
a. It is a result of the uneven partial charge diskbutton between verlen
in a compound
b. The strength between covalent bonding causes molecules to have poi
and nonpolar characteristics
Due to some exception, the sharing of electrons between storos in
covalent compounde results in a stable balance of attractive and
repulsive forces between atoms
d The structure of covalent compounds is unique that's why they can be
polar and nongolar
3. Which of the following explains the flammability of covalent
molecular compounds?
a. Covalent molecular compounds share their electrons forming poler
and nonpclar bonds
b. They contain carbon and hydrogen atoms that repot readily with oxygen
Because they generally have low melting and boiling points and the
addition
of a small amount of energy causes intermolecular attraction to
break d Molecules easily reactwith heat producing flames
